When you use a different 2.0 hub and when you do not use a 2.0 hub (And making Fx3 to work in 2.0 mode alone in the firmware), do you face this issue? Also, you can use any of our example projects for compliance testing. (typically USBBulkLoopAuto, USBBulkSourceSink
Hi Madhu, thanks for your reply.
It seems that the problem was caused by the hub. Many USB2.0 hubs (expecially the old ones) don't support the new L1 LPM, and this makes the test fail.
If I use a USB2.0 cable to connect the device and the USB3.0 host's port, the test passes.
Is there any app note for running USB2.0 electrical compliance tests on " EZ-USB FX3 CYUSB3KIT-001 " ?
Any quick help would be very useful.
Thanks and regards,
