Hi,
from the device side a low speed and a full speed device differ fundamentally.
They even differ in the way a resistor is connected to the USB data lines. You
can't just overwrite this by software. It's a hardware thing.

Hi,
you get that message if nothing but the speed-resistor is connected to
the host. The host detects the presence of the resistor and thus expects
a device to be present. It then tries to enumerate it and that fails.
You'd even get this message if you completely remove the FX2 from your

Hi,
which leads to the question: Why is the Enable Tablets entry not
inside the tablets menu. This way it's more obvious that it's disabled
if it's the only entry in the menu. Plus the parent menu gets
cleaned up as well.

What about devices that have serial numbers? Wouldn't it at least
be a good idea to make their file usage persistant?

USB devices can include a unique serial number allowing even devices
of the same kind to be distinguished.
Thus you would know that exactly the same device has been plugged in.

Sorry, i should have looked for that before asking.

Hi,
i have a similar card. I somehow figured out that this card in fact has 1k
sectors, not 512 bytes (i don't remember how, perhaps with a windows tool or
my palm ...). This happens with at least three different card readers which
is interesting, because my digital camera when being used as a

i am writing a driver for a usb to i2c bridge. The driver is working nicely
but i can still use my libusb based demo app to access the hardware
directly while at the same time the kernel driver is active resulting in
some confusion in both drivers. Since libusb accesses go unnoticed by my
