SubjectRe: 2.6.29rc1 breakes usb: hiddev device no longer available
> Since version 2.6.29rc1 querying cleware USb devices no longer works.
> 2.6.28 works fine. 2.6.29-rc2 also no longer works.

This is the WORKING situation:
open("/dev/usb/hiddev0", O_RDWR) = 3
ioctl(3, HIDIOCGDEVINFO, 0xbfa71a48) = 0
ioctl(3, HIDIOCAPPLICATION, 0) = -6291455
ioctl(3, HIDIOCGSTRING, 0x804e2c0) = 7

the is the FAILURE situation (2.6.29-rc*):
open("/dev/usb/hiddev0", O_RDWR) = 3
ioctl(3, HIDIOCGDEVINFO, 0xbf90c0d8) = 0
ioctl(3, HIDIOCAPPLICATION, 0) = -6291455
ioctl(3, HIDIOCGSTRING, 0x804e2c0) = -1 ENODEV (No such device)
