our LCD doesn't have any manual. we tried to change the base address on the code of lcdmod (from 0x378 to "/dev/usb/lp0", since the parallel to usb cable was detected as usblp), the error now is "LCD: no parport found at 0xc8136aff". we tried another driver (usblcd-0.1) and there, you have to put the vendor and product ID on the code. we typed the IDs of the parallel-usb adapter and it was detected. but then, it still didn't work. the value of usb_control_msg(with some parameters here..) is -1, which supposed to be >0. we think that the miniPC can only detect the parallel-usb adapter because it has the direct connectivity with the miniPC, leaving the LCD connected through that adapter undetected.
