After looking into it I discovered that it is based on the Prolific chipset using the PL2303 driver. I then checked the Vendor and Product ID against the list in the drive and sure enough, the IDs were missing in the driver. So here are my modifications to the PL2303 driver which have been working flawlessly on my system the whole week: drivers/usb/serial/pl2303.h -------- /* Radio Shack 26-183 */ #define RADIOSHACK26183_VENDOR_ID 0x05ad #define RADIOSHACK26183_PRODUCT_ID 0x0fba drivers/usb/serial/pl2303.c -------- Added to struct usb_device_id id_table { USB_DEVICE(RADIOSHACK26183_VENDOR_ID RADIOSHACK26183_PRODUCT_ID) } I still have to manually modprobe the module as the kernel won't automatically load it when I connect the device, no idea what I would need to change where for that to happen. The above though does successfully add support for that serial cable so I thought I'd share it with the kernel list so that it can possibly be added to the kernel and I can stop having to re-compile the driver every kernel update. :) Please feel free to contact me if needed. Thanks! Stephan
