USB Connect Problem

Hi

I am struggling at the moment to get the USB to my USRP board working
again. When I try to run any programs, it returns with

usrp: failed to find usrp[0]

My dmesg output looks like this when I connect my USRP:

usb 3-2: new high speed USB device using ehci_hcd and address 6
usb 3-2: unable to read config index 0 descriptor/all
usb 3-2: can’t read configurations, error -71
usb 3-2: new high speed USB device using ehci_hcd and address 7
usb 3-2: device not accepting address 7, error -71
usb 3-2: new high speed USB device using ehci_hcd and address 8
usb 3-2: unable to read config index 0 descriptor/all
usb 3-2: can’t read configurations, error -75
usb 3-2: new high speed USB device using ehci_hcd and address 9
usb 3-2: device descriptor read/8, error -71
usb 3-2: device descriptor read/8, error -71
usb 3-2: new high speed USB device using ehci_hcd and address 10
usb 3-2: unable to read config index 0 descriptor/all
usb 3-2: can’t read configurations, error -71
usb 3-2: new high speed USB device using ehci_hcd and address 11
usb 3-2: device descriptor read/all, error -71
usb 3-2: new high speed USB device using ehci_hcd and address 12
usb 3-2: can’t set config #1, error -71

I don’t understand what is happening, because it was happily working
not too long ago. I am using the 2.6.15-1-686 kernel. I have no problems
mounting my flash drive using the same ports. Also, I can load the
firmware via the USB1.1 ports, so I don’t think there is anything wrong
with the USRP. I am not that familiar with Linux, and I am really stuck
at the moment. Any help would be greatly appreciated.

Regards

Lance
