I recently tried to replicate the setup proposed in this instructable.
Everything is fine until I hook up the device into (any of) the USB ports. Then,
dmesg on Ubuntu complains that the device did not accept the address assignement (throwing an error
I tried to replicate the schematic here:
The only difference between this schematic and my actual set up is the
R3 resistor which in my case are two series resistors of
1k each. (
D3 was not present, but I thought it could be useful to see if the device was actually powered)
Why does Ubuntu recognise this as full speed rather than low speed? Do I need to use exactly the same resistance shown in the schematic, or do I have a completely different problem unrelated to this resistor value?
I'm a total beginner, so I may be missing something trivial, but I can't see it. Any help is appreciated.
P.S.: all components are SMDs
