Hi,
I'm trying to use a USB device over a Belkin network hub
<http://www.belkin.com/networkusbhub/>using libusbx-1.0.11-win and
WinUSB (v6.1.7600.16385) on Win7.
* My device is tested and working fine when connected directly to the
computer
* The device is also working correctly, with valid drivers in the
device manager
* I had my device working over the network hub when I used CDC serial
port emulation drivers instead.
* The problem seems to be that the network hub doesn't provide a valid
port number (in the device manager it lists the location as
"Location 0 (/Device-Name/)" instead of something like
"Port_#0001.Hub_#0005").
libusbx debug message:
[ 0.000000] [00001034] libusbx: warning [windows_get_device_list] could
not retrieve port number for device
'\\.\USB#VID_04D8&PID_0204#1&79F5D87&0&0000', skipping: [13] The data is
invalid.
This is probably not how libusbx is typically used but is there an easy
fix or could it be added to a future release?
* Could the lack of a port number be ignored? or the full address
string be used instead?
* I believe the relevant code is in windows_usb.c line 1306
Thanks,
Casey
