Topic: Howto - QinHeng Electronics HL-340 USB-Serial adapter

The content of this topic has been archived on 11 Apr 2018. There are no obvious gaps in this topic, but there may still be some posts missing at the end.

I have build myself a APRX Igate on a WL500gP V1, using openwrt Backfire 10.03, have set it up as a client (i use the 2.4 kernel and NAS) and made it to work with a Prolific Technology, Inc. PL2303 Serial Port  (USB to Serial converter)
However, I happen to own a couple of QinHeng Electronics HL-340 USB-Serial adapter adapters and do not know which driver to use. dmesg tells me:
usb.c: USB device 2 (vend/prod 0x1a86/0x7523) is not claimed by any active drive                                                                                                                               r.

Is there anyone who can help me out ?


The QinHeng Electronics HL-340 (ex. Orient USS-102) is a CH 340 compatible device.

opkg install kmod-usb-serial-ch341

As result:

[   20.000000] usbcore: registered new interface driver ch341
[   20.000000] usbserial: USB Serial support registered for ch341-uart
[   20.010000] ch341 1-1.2:1.0: ch341-uart converter detected
[   20.040000] usb 1-1.2: ch341-uart converter now attached to ttyUSB0

Thanks. I had solved the issue in the meantime, but nevertheless.

The discussion might have continued from here.
