The first number is the olde= st : revision in your tree, the second is the newest, and the M means you : have local modifications. Yes. Of course I have local modifications, but none in the usb stack. But I've also done a svn update from the top of the tree multiple times and this version number persists. : > Re another post: This is a 8GB flash, so I'm sure that there's enou= gh : > power. : = : Non sequitur. Bigger chips draw more power. Is it plugged directly : into the computer? If not, is it plugged into a powered hub? How ma= ny : other devices are connected to the computer or hub? Not entirely. This flash has worked in this computer in the past without issues (like a year ago when we were first integrating hpsusb into the tree). This flash is plugged directly into the computer. This behavior is consistent across multiple ports on the computer (so it isn't a bad port). While this doesn't prove it isn't a power issue, the odds are stacked against it being one. If there were a way to get the internal hub to tell me how much power it can deliver, and for me to query the flash to see maximum current draws, we could see if we're close to the edge or not...
