Hi, we are working on ti dm368,
sdk version is dvsdk_dm365_4_02_00_06
kernel version is 2.6.23.17
when we connect 4 or more usb serial devices (such as 3g modems, or usb to RS232 serial converter) on the same usb 2.0 hub,
we can see the kernel found ttyUSB0 ,ttyUSB1 ,, etc. seems all work well
and if we open the first three serial ports, it also works well
but when we open the fourth serial ports, it can only send data, while receive data will fail, from cat /proc/interrupt, we can not see the
usb interrupt when receiving data,
does anynon meet this issue before and found the solution? thanks a lot.
