I haven't done any power measurements but both models seem to work fine using the MK320 wireless keyboard/mouse combo connected to the network via Ethernet. It's only when I use the WiFi adapter on either model that I get the sticky and/or repeating key issue.Just as a matter of debugging, what is the power measured at the Pi, if you disconnect the wifi and connect directly thru Ethernet, do you have the keyboard issue and finally, have you tried using a USB extender cable so that you don't have 2 radio devices on top of one another?
That will tell you if the problem is hardware (not enough power) or software.rgvraspi wrote:I guess next step may be borrow the powered USB HUB from my PC to see if that improves things but as I didn't plan on attaching anything else to the Raspberry Pi it seems like an overkill just for this tiny adapter.

Yeh I have looked for help - i think it might be power supply issues! But I need a wireless USB and wireless keyboard but this thread doesn't inspire mesjfaustino wrote:First of all, have you requested any help with your issues with XBian?
I'm using 3 Pi's with no problems.
Second, good luck using a P4 800MHz with an Intel graphics card as an HTPC

But the dropped/stuck keys originally happened when using ethernet before I had mini-WiFi (different brand) directly on the Pi.
Interference came to my mind as well...vroberts wrote:Some of the problem may be related to the fact that the Logitech RF dongle operates near the same frequency as the USB WiFi adapter. The transmitter in the WiFi adapter may be overloading and interfering with the receiver in the Logitech adapter. The problem may be that the two RF adapters are right next to each other.
