USB Power switch no working

[ottowyrth]

Hello,

As there is no on / off button on the NOME II, i tried to add a cheap USB switch bought from Amazon but it doesn't work.
1. should it work, should I try another one?
2. NOME II is just not compatible with these things?

Produxct i tested:

Hi

There is no "official" list on these yet. The plan is to produce some ourselves and put them for sales on simntonic.com
I have tested a few, and they all worked, so I'm not sure why this particular one does not. It depends how the internal cabling is done - most of them simply cut the VBUS line, which cuts the power (i.e. same as unplugging the cable). These will definitely work.

What exactly happens when you press the button - nothing at all? And have you tested it on another device?
