Hello
I am using the following environment: Win7 64 Bit, C++ Bulk Loop Application and USBBulkLoopAuto firmware from the SDK V1.0 (no changes made).
Now I connect the FX3 through a Maxxtro USB 1.0 or 1.1 hub (not sure if it is 1.0 or 1.1) to a USB 2.0 port of my computer and download the FX3 firmware. I can then run the BulkLoop Application with 1024 Bytes transfer size and start value 2. No problem here. But when I switch the data pattern to "Random Byte", the application hangs after a few successful transfers. The same happens if I choose "Incrementing DWORD" as data pattern. Strange enough, "Incrementing Byte" works fine and also the C# BulkLoop application seems to work fine.
Can anyone repeat this behaviour? The FX3 should be USB 1.0 compliant isn't it?

Has really nobody tested USB 1.1 yet?

As Cypress is still trying to find the root cause, I wanted to bring this topic up again, asking if somebody encountered similar issues or has even found a solution/workaround.
