UCD9081: USB-TO-GPIO 2

Is there a version requirement with UCD9081RHBT Device GUI for using the newer USB-TO-GPIO2 ? 

Hi

USB-TO-GPIO2 dongle has not been verified on the UCD9081.

But there are couple things to check:

1. USB-TO-GPIO 2 need set to 100KHz

2. PEC feature shall be disabled on the USB-TO-GPIO 2 dongle

3. I recalled USB-TO-GPIO2 dongle default's pull-up is not configured, you may need configure it to 1K。

It is us holiday, team will test this after new year.
