USB Host problems


#1

Hi,

I can get the USB host to kinda work, ie fire the DeviceConnectedEvent() delegate but the disconnect delegate never seems to get fired when I remove the usb device(mem stick) ? Is this normal ? I need to restart the Fez Panda II in order for it to find the usb device again ?

Might I be doing something silly or has anyone else experienced this kind of behavior before ?

Regards,
Tom

Weak power?

You have probably already seen this, but I didn’t at first so I will post a link just in case: http://ghielectronics.blogspot.com/2011/03/usb-host-support-is-added-on-fez-panda.html

If you only looked at the Beginner USB host tutorial, you might have missed it. Without the mods, mine kinda worked, but was erratic… of course that was corrected after I hacked a USB adapter cable for the purpose.

Thanks for the suggestions guys. Made a new cable from scratch with the 2 * 15k pull downs and nice and stable with all the events firing…
