Hi,

Since I've updated my kernel to 2.6.32.10 I get the following errors in
dmesg:

...
btusb_bulk_complete: hci0 urb e48c1b00 failed to resubmit (1)
btusb_intr_complete: hci0 urb f201c280 failed to resubmit (1)

btusb_bulk_complete: hci0 urb f20ebf00 failed to resubmit (1)
btusb_bulk_complete: hci0 urb f20eb300 failed to resubmit (1)

I've had urb / isoc errors before and I've fixed that issue with isoc=0
on the 
kernel module, this parameter doesn't seem available anymore.

My HID devices are laggy and sometimes freeze for a minute.

Please help :)
