Hi,
I am using isp116x-hcd on an embedded device based on
mpc8xx on linux kernel 2.6.18. The hcd and cpu are
both low level triggered. While testing the hcd driver
with various usbtoserial convertors, I find that for a
large chunk of data transmission from my embedded
device to the host pc, the transfer stops after about
2 mins.
I have tried the following; but havent been
successful:
1. Changing the IRQ of the hcd from level to edge
triggered.
2. Applying the changes seen in isp116x-hcd.c upto
linux kernel version 2.6.22 on my kernel (2.6.18)
3. Changing delay values for the low level APIs
(isp116x.h)
The problem still persists.
Please let me know if anyone has faced a similar
issue.
Thanks,
Verano Rodriguez
