Using the test.sh script, I get a different result. According to USBMON, the test transmits the following: e0865c40 984311403 S Co:057:00 s 01 0b 0000 0000 0000 0 e0865c40 984318037 C Co:057:00 0 0 e0865c40 984320233 S Co:057:00 s 40 5b 0000 0000 0100 256 = 00010203 04050607 08090a0b 0c0d0e0f 10111213 14151617 18191a1b 1c1d1ee0865c40 984321033 C Co:057:00 -32 8 > e0865c40 984328828 S Co:057:00 s 01 0b 0000 0000 0000 0 e0865c40 984336037 C Co:057:00 0 0 e0865c40 984338146 S Co:057:00 s 40 5b 0000 0000 0100 256 = 00010203 04050607 08090a0b 0c0d0e0f 10111213 14151617 18191a1b 1c1d1ee0865c40 984339034 C Co:057:00 -32 8 > What's odd is that there is no reponse from the UDC. The dmesg output on the host shows this: usbtest 2-2:3.0: TEST 14: 15000 ep0out, 1..256 vary 1 usbtest 2-2:3.0: ctrl_out, wlen -32 (expected 256) So is this a problem with the test code? ------------------------------------------------------- This SF.Net email is sponsored by xPML, a groundbreaking scripting language that extends applications into web and mobile media.
