So, you definitely have a hardware problem. Digging for the id of your device 1043 8006 reveals a linux kernel mailing list archive thread: http://www.ussg.iu.edu/hypermail/linux/kernel/0410.0/0023.html with the identical problem: the device worked in some computer and not in other. I see two possibilities: a slave controller chip incompatibility or insufficient power problem, device wants to sink more current than port actually provides at +5V. Port should provide up to 500mA, while many notebooks are very weak at usb power and do not keep up the standard. To eliminate the first one, you should seek for the computer (or maybe an external usb hub) which will work with that chip. To eliminate the power issue on your equipment, you can try to measure consumption at the +5V with some prepared usb cable or even try to feed the device from an external power source. You will need laboratory equipment to do it (A regulated laboratory power supply with current limitation). Ask some electronics engineer. As a first aid, try an external usb hub with it's own power supply. 1G flash chips require a lot of power to operate, and not having enough is consistent with your symptoms of "no media". -- Petr -- gentoo-user@gentoo.org mailing list
