Bug Description

Ubuntu 15.10 kernel (4.2-0-27-generic) does not contain a driver for the "WinChipHead 13.56MHz RFID Card Reader and Writer" (ID 4348: 5537, Product name: CH374) but contains the driver for the older version - CH341 (ch341.ko) . The chip is properly recognized, but the lack of communication with him.
It's too bad, because thechip "WinChipHead 13.56MHz RFID Card Reader and Writer" is used in my Digital Storage Oscilloscope (DSO)
Regards - Janusz
