[zd1211-devs] [zd1211rw] Driver leaving device in bugged state ?

[Norman J. <zd...@de...>]

Hi,

could it be that zd1211rw ( kernel 2.6.18-rc4 ) leaves the device in a
bugged state ? The reason why I think so is that :

- When I power on the computer everything is fine and the driver module
gets loaded properly

- On every reboot afterwards there are error messages like this
usb 5-7: device descriptor read/64, error -110
and the driver doesn't load

- When the device is removed and plugged in everything works fine again
( like when powering on ... )

- Another driver ( ndiswrapper ) for the same device works fine under
all circumstances and never causes the -110 bug.

-> That bug simply starts appears only when zd1211rw has been loaded.

And I am not the only one experiencing it :

didn't start my cpufreq userspace program 'powernowd'. My usb dongle was 
still plugged in and it hasn't been properly initialized at boot time as 
you will see. then i replugged it and everything went fine again."

Note that system configuration ( acpi, pci, apic ) does not influence the problem.

Best regards,
