Public bug reported:
Binary package hint: linux-source-2.6.22
This was happening since the last Feisty kernel (2.6.20?) and still in Gutsy
2.6.22-14-386.
The symptoms have worsened somewhat over time which is quite disturbing, but I
don't think it's a hardware problem as I tried the adapter in a Windows XP
machine while my linux box wasn't recognising it, and it was configured
immediately.
When I insert the adapter, I get the following messages in dmesg repeatedly:
[ 80.666307] usb 4-7: new high speed USB device using ehci_hcd and address 34
[ 81.529673] usb 4-7: new high speed USB device using ehci_hcd and address 38
[ 81.790249] ehci_hcd 0000:00:1d.7: port 7 reset error -110
[ 81.790259] hub 4-0:1.0: hub_port_status failed (err = -32)
And sometimes (this was probably for a different port, but it doesn't matter
which one I use:
[ 317.075770] hub 4-1:1.0: Cannot enable port 3. Maybe the USB cable is bad?
(a few times).
No device entry shows up in lsusb.
The following script seems to work around it _sometimes_, but it appears
nondeterministic to me - I might try it 20 times before the card suddenly works.
"rmmod zd1211rw && rmmod ehci_hcd && modprobe ehci_hcd && sleep 1 && modprobe
ehci_hcd && modprobe zd1211rw && sleep 1 && dmesg|tail"
Eventually a successful case will look like:
[ 978.751143] usb 4-1.3: new high speed USB device using ehci_hcd and address 5
[ 978.843818] usb 4-1.3: configuration #1 chosen from 1 choice
[ 978.947003] usb 4-1.3: reset high speed USB device using ehci_hcd and
address 5
[ 980.488771] zd1211rw 4-1.3:1.0: firmware version 4725
[ 980.544735] zd1211rw 4-1.3:1.0: zd1211b chip 0ace:1215 v4810 high 00-11-e2
AL2230_RF pa0 ---N-
[ 980.547692] zd1211rw 4-1.3:1.0: eth1
[ 980.547956] usbcore: registered new interface driver zd1211rw
[ 981.026493] ADDRCONF(NETDEV_UP): eth1: link is not ready
(but the link will be ready).
thanks,
