USB2Test Question

[leitek]

Greetings,

I have a technical question on the USB2Test application, are you able to select the data packet transfer size ? Do you know what the size of the USB packet is being transferred ?

Thanks Keith

I don't remember the number off the top of my head, but it will be the maximum allowed for a USB frame in bulk transfer mode, for the speed negotiated with the host.

There is no option to change this in USB2Test, but there are some settings in the Windows O/S, which I have never played with, that claim to change the max size.

Further to David's comments, the USB2Test Loopback test and the USB 2.0 Loopback hardware transfer in blocks of 512 bytes of test data when in HighSpeed mode.
