Hi,

Lately I accidently broke USB power line in my Amstrad E3. I figured out that USB 5V output has around 45mA current limit.

I think some USB devices that require more power can not work properly when attached directly to the Amstrad.

I created a pdf document with some schematics and pictures of E3's 5V and 3.3V generators for those who are interesed.

regards
