Hi,

why do you think it is related to Rayer?

It seems to be similar to the concept of ft2232_spi but using another
USB bridge chip, namely CH341A.
http://wch-ic.com/download/down.asp?id=114

No idea if this stuff is related, but there are a number of
CH341A-based devices and programs:
http://sourceforge.net/projects/ch341eepromtool/
http://www.biosdiy.cn/wzcp/CH341Aenglish.htm
http://www.marcmart.com/ebay/o/OT757/OT757-USB_SPIsoftware.rar

Patches welcome... it certainly does not work *yet* with flashrom but
I don't see a reason why we could not add support for it.

I'm assuming the LPT port on the chip is in use.

I'll just order one and check it's PCB out.

Yours,
