Yes, you could be right. But let us assume there is only one
problem at a time :-)

I would like to apologize if I insulted you or anybody by saing "Linux
has a problem". I only meant to say that something strange is

I also said that it _appears_ to be a power

Looks better when I re-read it in mono-space - I guess the 100mA MxPwr

Hello everybody,
I have a similar problem with an external drive.
The drive gets its main power via a power supply, but unfortunately
