Hi I am using v-usb as part of a project on an atmega8.
When connecting the device to a rather old linux box:
Linux linuxpc9 2.6.18.2-34-default #4 SMP Sat Nov 22 09:31:31 CET 2008 i686 athlon i386 GNU/Linux
the device gets detected properly:
Jan 12 17:51:34 linuxpc9 kernel: usb 4-1: new low speed USB device using uhci_hcd and address 2
Jan 12 17:51:35 linuxpc9 kernel: usb 4-1: new device found, idVendor=1781, idProduct=0a97
Jan 12 17:51:35 linuxpc9 kernel: usb 4-1: new device strings: Mfr=1, Product=2, SerialNumber=0
Jan 12 17:51:35 linuxpc9 kernel: usb 4-1: Product: IRSND
Jan 12 17:51:35 linuxpc9 kernel: usb 4-1: Manufacturer: none
Jan 12 17:51:35 linuxpc9 kernel: usb 4-1: configuration #1 chosen from 1 choice
When trying the same device on Suse 11.4
Linux linuxpc2 2.6.37.6-24-desktop #1 SMP PREEMPT 2012-10-18 22:36:08 +0200 x86_64 x86_64 x86_64 GNU/Linux
I find the following in /var/log/messages:
Jan 12 18:06:36 linuxpc2 kernel: [ 4934.092252] usb 1-10.6: new low speed USB device using ehci_hcd and address 18

Jan 12 18:06:37 linuxpc2 kernel: [ 4935.362188] hub 1-10:1.0: unable to enumerate USB device on port 6
Any hints on where to search? Am I missing some kernel/modules?
Thanks
Wolfgang
