Hi,
I have the following problem:
I use a Prolific PL2303 based USB2Serial adapter on my WL500gP.
If I connect it directly to my box everything works fine.
dmesg:
Code:
usbserial.c: PL-2303 converter detected
usbserial.c: PL-2303 converter now attached to ttyUSB0 (or usb/tts/0 for devfs)
But if I use this device with a USB hub connected to my box I get the following error message.
dmesg:
Code:
hub.c: new USB device 01:03.2-2.1, assigned address 4
usb.c: unable to get device descriptor (error=-32)
hub.c: new USB device 01:03.2-2.1, assigned address 5
usb.c: unable to get device descriptor (error=-32)
It seems that the USB2Serial adapter is only be identified correctly if I connect it directly to the USB port of the WL500gP, but fails if I use it with an USB hub.
The USB hub itself seems to work correctly:
dmesg:
Code:
hub.c: new USB device 01:03.2-2, assigned address 3
hub.c: USB hub found
hub.c: 4 ports detected
I also tested this hub with my USB memory stick with no problems at all.
Questions:
* Is there anyone else out there having the same problem and probably a solution too?
* Is there anyone using a PL2303 based USB2Serial adapter successfully in combination with an USB hub?
* Does someone know a working solution for another USB2serial adapter, which is supported by the WL500gP firmware and works with an USB hub?
Any help is higly appreciated.
Thanks,
Gecko.
