I found that I am using libusb-win32 version 0.1.12.0-1, I change it
to version 0.1.10.1-3. I plugged TX and RX in my USRP device. but I got
this error.
$ python test_counting.py

Subject: [Discuss-gnuradio] Error in my first USRP test
Hi
I tried to run test_counting.py , I got the folloing message
$ python test_counting.py
usb_control_msg failed: usb_control_msg: sending control message
failed, win err
or: A device attached to the system is not functioning.
usb_control_msg failed: usb_control_msg: sending control message

As far as I can tell, one occurrence of this error each time you start
GNU Radio is normal when using Windows libusb 0.1.12. I don't know
why you get two of them.
gr_check_counting: enter_SEARCHING at offset 0 (0x00000000)
gr_check_counting: expected 0 (0x0000) got 2 (0x0002) offset
0 (0x00000000)
gr_check_counting: expected 3 (0x0003) got 3 (0x0003) offset
1 (0x00000001)
gr_check_counting: expected 4 (0x0004) got 4 (0x0004) offset
2 (0x00000002)
gr_check_counting: expected 5 (0x0005) got 5 (0x0005) offset
3 (0x00000003)
gr_check_counting: enter_LOCKED at offset 3 (0x00000003)
This is also what I get. I have assumed it is normal.

Could you please what is wrong
