Yes, I have tried powered hub also...even made well regulated power supply myself so my guess is power was not problem...by the way I have a feeling that usb problems have been less since I updated Raspberry's os. (But audio receive quality is still a bit poor) Gunnar, By the way... maybe it is my bat english but I am little confused about your instruction. I have download 1.5.10 From http://www.crusefalk.se/jpskmailinstall/ But it is executable file, when I try to execute it, pi gets busy for a while but nothing seems to happend. If I try executing from root terminal, it says "binary file cannot be executed"... so I cant find any "jpskmail lib" so I can not open javapskmail.jar :D I feel stupid :D Should this installer be runnable and make some directory containing those javapskmail.jar etc. ? (I have made permission to run this file.) This is what I meant, I can not find 1.5.10 jar files. I can see previous version I have tried while ago have been jpskmail installer 1.6.10, it do exactly same, nothing:) Tarmo, OH6ECF 2012/12/27 Larry Levesque <ka1vgm@xxxxxxxxx> > I suspect it is a power issue. > > Try plugging a powered usb hub into the PI and the sound card into that. > > The recommended power supply is at least 1amp for the Pi but it only > supports powering a level less than that for devices. > > Other people with similar problems have cured it by replacing the power > supply or using the powered usb hub. > > Larry Levesque > KA1VGM > Cheshire County EC > NHARES > > > On Wed, Dec 26, 2012 at 3:23 PM, Tarmo Huttunen <tarmopaha@xxxxxxxxx>wrote: > >> Well, I haven't got jpskmail working on raspberry yet.
