+ Sadly, the WMB13U-868 dongle uses a prolific pl2303 USB2Serial converter
+ and it seems like there are bugs in the linux drivers for this converter.
+ Or the device itself is buggy....
+ Anyway, the dongle works when first plugged in, but if
+ the ttyUSB0 is closed and then opened again, it most likely
+ stops working.
 
+ So the dongle can perhaps be used like this:
+ configure the dongle using the Windows software to use your
+ desired C1 or T1 mode. Then plug it into your linux box.
+ This driver intentionally does not write to the dongle,
+ if you are lucky, the dongle might receive nicely and
+ not hang.
