Although still hang on bf527 v0.2, there is no kernel dump any more.

/064 -t7rc/testusb -D /proc/bus/usb/005

unknown speed /proc/bus/usb/005/064

timeout: testusb t7

Last passed test result is not found!!

Case 15 ...FAIL

--- Cliff Cai 2009-05-18 04:15:21

This bug is the same with bug #4924.The problem exists in the

empty_out_buf()usb.c.When one of the read data is not equal to expected

value,the following code in empty_out_buf() is badly wrong:

for (i = 0, data = 0; i < nbytes; i++, data++) {

if (0 == (i % 16))

fprintf (stderr, "%4d:", i);

fprintf (stderr, " %02x", *data);

if (15 == (i % 16))

fprintf (stderr, "\n");

}

data is a pointer,"data = 0",should be "data = buf".

It's OK now. Close it.
