. General questions:. What types of USB devices are supported in Oracle Solaris?

1. Uc Sgt Driver

Refer to usb(7D) man page which lists all bundled USB drivers. What is the latest version of Oracle Solaris and how to get it? Is the latest release of Oracle Solaris -. My device does not enumerate and I get the message 'connecting device on port failed'.

Uc Sgt Driver

What is the cause? Often the root cause is that the device is not USB spec compliant but there are a few things to check:.

if connected to usb1.x port then connect to usb2.0 or vice versa. insert a usb1.x or usb2.0 hub. if a usb2.0 device is on a usb2.0 port you can force it to usb1.x speed by inserting a usb1.x hub.

if a 1.x device is on a usb1.x port you can force it to work usb2.0 ehci driver by inserting a usb2.0 hub. use better cables. use shorter cables.

How do I diagnose USB problems? Mdb(1) has a dcmd::usbadebugbuf for dumping the USB log buffer which may give some hints on what went wrong. You should also check /var/adm/messages. My device is not responding.

How do I check if my USB device was recognized by the OS? What command can I use? You can use 'cfgadm' to find the port that your device is connected to.

See the man page cfgadmusb(1M) for details. # cfgadm -vl # cfgadm -c disconnect usbx/y # cfgadm -c configure usbx/y # prtconf -D. Can I do soft hotplugging (without physically disconnecting the device)? # cfgadm -vl # cfgadm -c disconnect usbx/y # prtconf -D The device node should no longer be listed. Refer to cfgadmusb(1M). (Note: In some cases, the cfgadm disconnect will not make the devices soft hot plugged.). On my SPARC platform, when I don't use my device for an hour or so, and try to use it, it is not working.

On SPARC platforms power management may have powered it down. Edit the file /etc/power.conf, disable autopm, and run pmconfig or reboot.

This is applicable only in Oracle Solaris 10; in Oracle Solaris 11 device power management is not supported. I get 'Connection failure' warnings when I connect my device and it does not work. Run prtconf -D on the command prompt and check if the device enumerated.

If you have an older SPARC machine with USB 1.x ports, possible workarounds are connecting the device to a USB 1.x port or connect a USB 1.x hub and then the device to this hub. This forces the device to be managed by ohci or uhci. If users do not need USB 2.0 support, another workaround is to run the below command which disables the ehci(7D) driver: # remdrv ehci. I need a USB to PS2 converter.

Any suggestions which ones work well? We have seen that the Cables Unlimited and SIIG USB to PS2 converters work well. I have a 5m cable. Should it work? It may with most devices but may be flaky with bus-powered devices such as the Oracle mouse. I need to extend to 100m or more.

How do I use this? You can use active cable extenders. How do I disable all USB ports?

To enforce security, refer to usbsecure.pl script To completely disable USB, you can remove the USB package with the pkgrm command. How do I configure my USB printer on Oracle Solaris 10? On Oracle Solaris 10, you may use print manager, /usr/sbin/printmgr command. Or use JDS Java Launch - Preferences - Printer Preferences. On Oracle Solaris 10, this message confuses me.

'USB 2.0 device (usbd49,7010) operating at full speed (USB 1.x) on USB 1.10 root hub: storage@2, scsa2usb1 at bus address 2'. Please clarify. This means that a USB 2.0 device is connected to a USB1.x hub which is operating at full speed (and not at high speed), because the USB1.x port only support full speed and low speed. Can I boot from a USB disk or USB CD/DVD drive? Generally speaking, booting from USB disk, CD/DVD drive is supported on x86 platforms with S10 update 1 and later if the BIOS has USB 2.0 support.

Sparc systems with USB 2.0 support can boot from USB disks if the OBP(Open Boot Prom) is upgraded to version 4.27 or later. Before you can boot Oracle Solaris from USB disk, you have to install Oracle Solaris on the disk first.

Installing on USB memory sticks is not recommended as the number of writes to these sticks is limited. Problems observed on some hardware platforms:. Installation from USB CD/DVD drive starts, but then fails with 'not finding media' error. This is because the CD/DVD drive is not mounted under the /cdrom directory as the installation process expects. Possible workaround is to re-plug in the CD/DVD drive, and make sure the device is in the device tree and the /dev/dsk/ link is correctly created, and mount it under /cdrom manually, then continue installation by /sbin/install-solaris.

Installation to USB hard disk seems slow and then hangs somewhere. Check dmesg output if there are repeatedly 'timeout' and 'tranerr'. Such error messages would mean you don't have enough physical memory.

The workaround is to install more than 512M physical RAMs or to use S10U2 or later. These releases contain the ehci fix for USB 2.0 disk support.

Booting from USB hard disk panics on 'cannot mount root path'. Check if the disk is connected behind a USB hub. Don't use a hub between when booting from USB disk.

And check if the bootpath in /boot/solaris/bootenv.rc matches the USB disk drive path. If not, modify bootenv.rc, boot into failsafe and make sure bootarchive on the USB disk drive is updated. How do I boot off a USB disk for an x86/x64-based server?

Assuming you are using a Oracle X-line server utilizing an American Megatrends, Inc. (AMI) BIOS, press F2 at server bootup to enter the BIOS. Navigate to the Boot menu option using the arrow keys 1. Hit return on Boot Device Priority 2 and hit return again with the 1st Boot Device selected 3. You should see your USB device listed. Highlight it and press enter, then F10 to Save and Exit 4.

This will reboot your server using your USB disk as the primary boot device. If your USB device is not showing up in the Boot Device Priority menu, try seeing if it is listed in the Hard Disk Drives section under Boot. You should be able to hit return on 1st Drive and see it listed 5. If it still is not visible, you may want to check if your USB disk is USB 2.0 compatible, or alternatively, try upgrading the BIOS to a newer version.

This method is not exclusive to Oracle servers. Any BIOS that supports booting from a USB 2.0 device should theoretically work with this method, although the exact menu layout may differ. It is also worth noting that USB boot works equally well with both external and internal USB ports 6. On many 1U-based Oracle servers with internal slots, the bottom port is inactive.

Use the top port for your USB device. How can I get the product id and vendor id of a USB device? Connect the device to the host and check the file /var/adm/messages for messages like: Aug 12 17:18:19 mysystem usba: ID 912658 kern.info USB 2.0 device (usb781,5151) operating at hi speed (USB 2.x) on USB 2.0 root hub: storage@6, scsa2usb0 bus address 2 usb781,5151 gives you the vendor id (0x781) and product id (0x5151). Or check prtconf -v output for something like: name='usb-product-id' type=int items=1 value=00005151 name='usb-vendor-id' type=int items=1 value=00000781 name='compatible' type=string items=9 value='usb781,5151.20' + 'usb781,5151' + 'usbif781,class8.6.50' + 'usbif781,class8.6' + 'usbif781,class8' + 'usbif,class8.6.50' + 'usbif,class8.6' + 'usbif,class8' + 'usb,device'.

When I connect my device to the USB ports on the front panel of my SPARC machine sometimes, it does not work. But the same device works when connected to the USB ports on the back panel. This is most likely caused by some hardware incompatibility issue. To work around the problem, either connect the device to the front port via a USB hub or connect the device to the back port of the SPARC machine. What is usbmid? Refer to usbmid(7d) man page. Usbmid is the default driver and is a multi interface driver.

It checks if each of the 'interfaces' on the device can be bound to a driver. It also exports a ugen(7D) interface (Oracle Solaris 10 Update 2 and later) so the device can work with libusb(3LIB). Can I use a USB modem? Support for USB modems and ISDN terminal adapters that conform to the Universal Serial Bus Communication Device Class Abstract Control Model (USB CDC ACM) specification is available in Oracle Solaris 10 Update 4. See the usbsacm(7D) man page. What is USB ECM? USB CDC-ECM(Communication Device Class - Ethernet Control Model) is a class of device that can exchange Ethernet frame data with the host.

CDC-ECM device has a MAC address and is configurable. With usbecm(7D) driver, it is identified by host software as a NIC interface. Users can use standard Oracle Solaris network administration utilities to manage this interface.

The USB CDC-ECM device is only found in servers which have ILOM or SP-like remote console. It's kind of a virtual device and is used to provide a high bandwidth connection between host and Service Processors on Oracle platforms.

On which Oracle servers could users make use of this feature? USB CDC-ECM device can be found on the newer Oracle servers.

This interface provides a high bandwidth link between the host and SP. Oracle Solaris ILOM management tools,such ilomconfig(1M) relies on this interface to manage ILOM on Oracle servers. You can find ECM interface on Oracle SPARC T3/T4 series and oracle X86 X4170/X4270 etc. Users may also find such an interface on other vendor's servers as well. How can users use this feature, can you provide an example usage?
