Are there any
devices created ?
There are multiple /dev/usbXXX.X type files, but no /dev/ttyUSB* type devices.
The 3G usb card is seen in the Diagnostic USB page 5 times, but not on the Network config setup page.
Attached is a TSR for the SG560U with just the password set from a factory erase.
Yep, a driver issue.
I'll see if I can get some feedback on if one is readily available.
