On Raspberry Pi B + only with tricks, but then ...

The stick was right on Pi + B does not function. It came I / O error after tuck always a Network.
The under OpenELEC Gotham and Kodi (4.x and 5.0).
However dmesg shows the detected the drive and the drivers are loaded, then came a lot of error messages,
It requires no additional drivers from the manufacturer. The error thus lay elsewhere.

Manual configuration (Putty and vi) under /storage/.cache/connman/mywlan.config
being "myWLAN" of its own network name
with the content

[Global]
Name = myWLAN
Description = myWLAN Wifi service config file

[Service_wifi_mywlan]
Type = wifi
Security = WPA2-PSK
Name = myWLAN
Passphrase = My_passphrase

secured a WPA2 network then brought sporadic success, the next time the connection was back mit.og off errors. (Then the wired network must be in OpenELEC deakviert - Programs - OpenELEC - configuration).

This stick I had sent back because the EW-7612 should Uan (without V2) function supposedly, but I had another V2er.

After 2 weeks of trial and error with the futile old then I got enlightenment.
Only when operating with an external USB hub with its own power supply (2A) brought the stick to work properly.

There is, however, the stick worlds better than the highly praised EW-7811 (Mini USB wireless stick).

But the problem appears mainly on Raspberry Pi B + (rare at the old B) occur.

Because of this quirk only 4 stars.

On PC and Notebook gibts 5 stars, where he works for uploading the driver immediately.
