Dear Greg:
I have the upload speed problems about the data card modem.
For the data card modem we used, it can support the upload speed up to 5.76Mbps and download speed up to 7.2Mbps on the Windows OS.
And on the Linux OS, such as OpenSuse or Debian, we load the kernel usb serial driver "option.c" for the modem, and we can get the download speed up to 7.2Mbps.
But no matter what we do, the upload speed will still be 1.5Mbps, but not 5.76Mbps. And I don't know why it is 1.5Mbps, but not 5.76.
Can you help me to find what results in this?
Thanks very much.
Best Regards,
Franko Fang
