Hello,
When I plug in an Alfa AWUS051NH USB wireless card, "iw dev" shows phy0 for a moment, then phy1, phy2, etc. If the card is not unplugged within about 10 seconds, the system locks as if out of memory. When looking at "dmesg" output, it can be seen that the driver loading process is occuring repeatedly; perhaps infinitely until the system lock occurs. Please see a section of the dmesg output below. On each loop there are warnings "rt2800usb_entry_txstatus_timeout: Warning - TX status timeout for entry 0 in queue 0" that others appear to be having trouble with, but not reporting the looping issue. In most cases "Googled", the warning appears, the card doesnt connect and that is the end. In my case, the loop occurs.
Please advise if there is a way to fix or at least a way to prevent the loop to allow more diagnostics.
dmesg output with card being plugged in twice for about 5 seconds per time (anymore risks locking the system)
