Which USB hub - powered or not

Postby yildizabdullah » Fri Aug 01, 2014 8:51 am

My board SKU number is A101020.

I use S-link SL-U90 USB hub but it didn't work. Am I supposed to use a powered USB hub? By the way, USER LED CR10 and HDMI work properly.

I also noticed that USB_PWR_GD CR4 is OFF.

Is it possible that the board is damaged?

The board schematic says that P0_VBUS is output from MIC2025-1YM.

Hi,

I switched to a powered USB hub which is not certified by Parallella but it works. CR4 still does not work.
