Dear All，
We met a problem of 3G modem uploading speed.
kernel version is 2.6.19 ,using option.ko , and we have changed
N_OUT_URB to 4 and OUT_BUFLEN to 1024 and some modification
according of 2.6.29.
Using this site to test uploading speed:
http://www.linkwan.com/gb/broadmeter/SpeedAuto/gotoSpeed.asp?SpeedUserId=65356
and the result of uploading speed is about 300kbps. and in
windows xp its uploading speed is 800kbps.
in the code:
if (test_and_set_bit(i, &portdata->out_busy)) {
//printk("i=%d,time=%d\n",i,jiffies-portdata->tx_start_time[i]);
//printk("urb busy,left=%d i = %d \n",left,i);
if (time_before(jiffies,
portdata->tx_start_time[i] + 10 * HZ))
continue;
usb_unlink_urb(this_urb);
continue;
}
if using printk during test, it may tell us urb busy.
anyone can give some help or any suggestion?
best wishes
paul
