Hi,

It does not seem to implement PPCLAIM/PPRELEASE ioctls, used e.g. in 
ppdev.c. So I don't think it can be used like a generic parport. There 
are other ioctls to switch between operation modes like parallel, mem, 
i2c, spi.

Support for SPI might be especially interesting, as it can be used as 
JTAG under certain circumstances, e.g. if one can toggle between GPIO 
and SPI mode freely.

However, support for such CH341-specific mode in UrJTAG would be either 
Linux-only (using the kernel driver you referenced) or implementing the 
functionality using libusb, as you suggested.
