USB dongles not enumerating

Former Member
Former Member over 9 years ago

Hi, I am having problems with a couple of WI-FI USB dongles that, when connected to the microzed board running Linux, do not get enumerated (the protocol is stuck very very early in the process).
If I put an hub in between all works fine.
Has anyone experienced anything like this? many other dongles work flawlessly but two of them (D-Link DWA-140 and Edimax EW-7718uN) don't.
Obiously the two dongles work everywhere else.

The same problem replicates on our custom board that was developed as a close copy of the microzed so it must be a design or component problem (phy related?)

Any information would be very much appreciated,
thanks
Jo

    Hey Gary.

    I don't think that it could be a power problem, because when the (unpowered) hub is in between, it can easily handle not one, but three dongles, including the mentioned two that without the hub would not work.
