Hello: My system is suse linux 10.0 with kernel 2.6.13-15.8-default. THe system has usb 1 and usb 2 interfaces. I have the following problem: If I plug in my usb mp3player/cardreader (no internal memory, only SD card) when an SD card is inserted the player can't connect, the display of the player remains blank. If I plug in the player with no inserted SD card the player can connect and the player's display states the the unit is connected. If I insert the SD card after this the SD card is recognized and I can mount/ read/write. I googled and found different results, some saying that this caused by kernel bug. I would like to see clear if this is really a kernel bug or something else and how could be fixed. Here are the dmesg messages (only last few lines): 1.
