Comment 2 for bug 439856

here: Ubuntu 9.10, Kernel 2.6.31-14-generic, MSI Wind 100

device is SOMETIMES visible in lsusb as
Bus 001 Device 004: ID 5986:0141 Acer, Inc (Acer = vendor of BisonCam NB Pro), but it doesn't work!

and SOMETIMES randomly it is not visible in lsusb. it's even worse, because then
IT AFFECTS OTHER USB-PORTS (see attached an extracts of dmesg)

and I can't use any of them. a reboot helps putting the ports up again.
if you need further information please contact me,
regards, edde
