Hi all,
we are using eagle-usb driver with kernel 2.4, frequently we lost
frames on ping. From the usb-analyzer we seen that the frame of
response sometime was assembled badly by usb-modem. Following are
the trace of usb-analyzer:
1) response received, so ping successful, the frames from modem
are:
64 bytes (02 80 02 30...)
64 bytes (12 13 14 15...)
31 bytes (00 00 54 92...)
2) response not received by eagle (non integral number of cell),
the frames from modem are:
63 bytes (00 80 02 30...)
64 bytes (11 12 13 14...)
32 bytes (45 00 00 54...)
Case 2) the total bytes are correct, but were assembled badly. For
our usb controller, a less 64 frame was considered end of packet,
so the response of the ping was split into two packets, 63 bytes
and 64+32 bytes.
Is there anyone has had same problem? Is there any new firmware
that fix the problem?
Thanks in advance,
Jianliang Lu
