Hi everybody,

I have an error message with 2.6.23-rc6.
This did not happen with 2.6.22.

The kernel reports message like this:
<3>usb 1-1: device not accepting address 2, error -62
<3>hub 2-2.1:1.0: hub_port_status failed (err = -71)

Does this message harm or is something broken in 2.6.23-rc6 ?
I get this kind of messages also with 2.6.23-rc3

Best regards,

Christian

Please see below for:

grep -e hub -e usb boot.msg for a 2.6.23-rc6 boot. (that boot was without (err = -71)
grep -e hub -e usb boot.msg for a 2.6.22 boot.
lspci -vnn (2.6.22)
lsusb -v (2.6.22)
