RT3070 defective?

[Dominik]

I tried to get the RT3070USB to work with rt3070 driver from ralink.com. I think my device was defective.
At kernel bootup it pauses a couple of time and I got this messages:

Code: Select all

And at lsusb I cannot see it anymore:

Any idea, what I can do?

Problem solved yesterday!
Shutdown and reboot after a couple of time were not enough. Yesterday I accidentally pull out the power plug. Now the kernel boots straightly again. I already bought another wifi usb-adapter, so I won't try any more to get the rt3070 work in next time.
