PL2303GL device not working #363

Open signdevfahad opened 1 year ago

signdevfahad commented 1 year ago

Hi, Just wondering if this lib works with PL2303GL driver devices. VID: 1659 PID: 9171 Because I have tried but the connection is not opening with it.

I am using this lib for a couple of years in my product and really appreciate your work.

Having the same problem with an ATEN UC232A serial adapter, VID: 0x067B (1659) PID: 0x23A3 (9123).

ATEN support claims that this particular adapter is using a newer chipset than the same model from earlier.

It works fine in other Android apps, such as "Serial USB Terminal".

Note that I'm using the Flutter plugin usb_serial, which seems to be using UsbSerial under the hood.

ATEN have provided some kind of "driver" (jar files) and examples for Android on their website, perhaps those could be of use for adding support for these newer chipsets?
