So much USB commands
« on: July 29, 2013, 05:48:46 pm »
Hi Jan,

Do you know how many commands per second of the USB 1.1 can handle before it breaks?

I'm using Silabs F381 mcu and I'm sending a lot of commands and quickly get a reply of it and the firmware behaves unexpectedly somewhere in the middle, there are bits that was turned OFF which supposed to be ON, I am using Busdog usb trace.

Thanks in advance

I don't know of any limit on the number of commands USB can handle, apart from the number that can be physically transmitted across the wire.

I don't think your problem is with USB, but with the firmware on the device. I would be unsurprised if the firmware on your device can't cope with back to back commands.
