SV-huMMer, thanks for the reply to my question, Xperia TL via USB versus Clip Zip. After I posted it I realized the many variations of this, some using UARP, others using custom ROM's and kernels, etc. Anyway, I received my OTG cable today and my Xperia TL connected to my Audio GD NFB12 DAC/AMP, displayed the same USB power consumption error. I have read your various posts and analysis of the issue. Are you using the generic USB hub to fool your Sola or the small powered hub Danba suggested? BTW the link in his post for Dr. Bots T-3 doesn't work. I wonder if anyone has tried the hifidiy Sabre dac, perhaps its power consumption is low enough to work with the Xperia. Does the power consumption error indicate the TL will work in OTG if the power issue is resolved? Thanks for all your research. I love my Xperia TL, and would like to use it. satwilson
I use the generic hub, it's in the pic I posted. In fact, I have tried two generic USB 2.0 4-port non-powered hubs, and they both worked. I chose the one in the pic because of smaller enclosure that is easy to open and close, and I will do some resoldering to get rid of as many connectors as possible.
As for other dacs, it's a hit and miss, but remember that the important thing is not how much current the device really draws, but how much current it claims from the host.
True, and it alsp depends on the cellular network strength. If the network coverage is great, the phone does less seeking. The weaker the coverage, the more hunting and the more noise.
