usb.USBError: Connection timed out

The only modifications I did was removing the french and german records.
I'm using ACR122U-AU and ACR122T-E2

Please try again with the newest revision on trunk. There's a couple of changes made and I can only trace things based on that version. Thanks a lot.

There is no new information whether this bug still exists. It was either implicitly fixed by some later update or the devices ACR122U-AU and ACR122T-E2 are not supported (only ACR122U-WB-R and ACR122U-A9 are available for testing).
