Hello,

We released an application using HID in uPSD. However, we faced to a problem that our product doesn't run on the system supporting fast USB 2.0. Furthermore, the document, DK3200-errata-0303.pdf is announcing this problem.

Please check it and give me some advice about it.

Best regards,

Byounghoon

As I investigate, only Intel chipset has problem with uPSD's HID module. In VIA chipset, there is no problem in connection.

Best regards,

We have an engineer currently working on the fix to the problem number 3 described in DK3200-errata-0303.pdf document. The firmware fix should be ready in a few days.

Hello,

Testing DK3200 Development Board, it works. As you konw, DK3200 Development Board using external power to communicate with PC, however our application lead the power just from USB cable. We need 500mA to operate our application.
