UWN200/MT7601U: lsusb -v hangs


Thanks to Robert, I got the driver for my UWN200
(MT7601USTA Ralink) Wifi USB dongle compiled and
I can "see" the WLANs around me.

One thing remains:
Doing a

But doing a
    lsubs -v

hangs. Last entry listed:
    Bus 001 Device 003: ID 148f:7601 Ralink Technology, Corp.
    Device Descriptor:
    bLength 18
    bDescriptorType 1
    bcdUSB 2.01
    bDeviceClass 0 (Defined at Interface level)
    bDeviceSubClass 0
    bDeviceProtocol 0
    bMaxPacketSize0 64
    idVendor 0x148f Ralink Technology, Corp.
    idProduct 0x7601
    bcdDevice 0.00
    iManufacturer 1

The "X" marks the position of the cursor on the screen.

I am using Gentoo Linux, Robert Nelsons kernel 3.8.13-bone67
and Robert Nelsons version of the MT7601USTA Ralink/mediaThek

Is this "quite normal" (using this driver reveals this problem),
or is it "my driver" with this problem?

Thank you very much for any suggestion!
Best regards,
