unixware 7.1.3 I'm afraid ! I connected a usb tape drive and it was automatically recognised in the device list (sdiconfig -l) and created devices in /dev/rmt (ctape1 etc.). I could successfully read and write to the device.
Then unplugged the usb cable and plugged it back in again to the same port. This time the device is still in the device list but the entries in /dev/rmt have gone and these messages appear on the console when the usb cable is connected:
I've tried re-booting the machine but still no devices. I'm guessing that the problem is related to the "Descriptor load failed during enumeration!" message. Any ideas on how to fix this problem and recreate the /dev/rmt entries ?

edit by bakunin: please use CODE-tags for code, terminal output and the like, nothing else. Thank you.

When I attach a USB storage device to my Solaris server, the mount point is coming up as /rmdisk/unnamed_rmdisk
Is there anyway I can have this device come up as a mounted device with a predetermined mount name eg /morespace rather than unnamed_rmdisk ? (0 Replies)

Hello,
I need to run an application in wine that requires write permission to a USB device. Wine users must not have root privileges. On FreeBSD this could be accomplished by adding the user to the wheel group but I am using Debian 6.0. From looking at the passwd file it is not obvious what... (6 Replies)

lsusb
lsusb(8) Linux USB Utilities lsusb(8)NAME
lsusb - list USB devices
SYNOPSIS
lsusb [ options ]
DESCRIPTION
lsusb is a utility for displaying information about USB buses in the system and the devices connected to them.
OPTIONS -v, --verbose
Tells lsusb to be verbose and display detailed information about the devices shown. This includes configuration descriptors for the
device's current speed. Class descriptors will be shown, when available, for USB device classes including hub, audio, HID, communi-
cations, and chipcard.
-s [[bus]:][devnum]
Show only devices in specified bus and/or devnum. Both ID's are given in decimal and may be omitted.
-d [vendor]:[product]
Show only devices with the specified vendor and product ID. Both ID's are given in hexadecimal.
-D device
Do not scan the /dev/bus/usb directory, instead display only information about the device whose device file is given. The device
file should be something like /dev/bus/usb/001/001. This option displays detailed information like the v option; you must be root
to do this.
-t Tells lsusb to dump the physical USB device hierarchy as a tree. This overrides the v option.
-V, --version
Print version information on standard output, then exit successfully.
RETURN VALUE
If the specified device is not found, a non-zero exit code is returned.
FILES
