Since some days my serial port has a problem and I am not able to use my local printer. I got aUSB printer adapter cable and expected that that would solve my problem. I started Yast and expected to find the USB connected printer. No printer detected, even with the printer wizzard under the USB connection. Lsusb shows : "Bus 002 Device 004: ID 4348:5584 WinChipHead CH34x printer adapter cable". Is there some trick?
I may be wrong, but this looks like it was a usb-to-parallel adapter; I would expect 4348:5523 for the winchiphead usb-to-serial adapter. Is there anything that would allow you to set the mode of the cable (e.g. CH341 supports both parallel and serial)?
Could somebody tell me how to proceed?
Is the correct module loaded (I think you need usbserial in case of a serial adapter, or usblp in case of a parallel adapter)? have you tried to setup the printer manually via cups's admin frontend at http://localhost:631? you should also check what happens in the system log when you plug in the USB side of the adapter (e.g. modules loaded, printer device node created ....)
Thanks Karl-Heinz,
On the adaptor is written that it is a Parallel Printer connector, the type with a very wide mouth which is hooked to the printer with two wire clamps. Tried already to manually set the printer up with cups with the same type of silence. Does not seem to have anything with which it to set the mode of the cable. If I connect the usb cable to the computer I get enough info to get the idea that a connection is detected and that usbpl seems in use. I connected and disconnected several times and invariable get something like the following in the log:

After a reboot I get following: dmesg |grep usb <snip> [ 23.399198] input: sonixj as /devices/pci0000:00/0000:00:03.1/usb3/3-3/3-3.1/input/input6 [ 23.428829] usbcore: registered new interface driver sonixj [ 26.899071] usblp0: USB Bidirectional printer dev 2 if 0 alt 0 proto 2 vid 0x4348 pid 0x5584 [ 26.917056] usbcore: registered new interface driver usblp [ 176.485892] usblp0: nonzero read bulk status received: -62
Some of this info should give a hint how to proceed. Any ideas?
It would seem you need to connect to usblp0 not just usblp. -- Ken Schneider SuSe since Version 5.2, June 1998 -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org
