Hi, I am trying to mount a usb flash drive on Athena. Specifically, I'm trying
right now on one of the hp machines. When I tried to attach consult and run atta
ch-usb, I got the error that no usb's were recently connected to the computer. I
s there something else I can try? Thank you, Joel

What's wrong:
attach-usb does not seem to work on HP workstations. I only checked using the top USB port immediately to the right of the Ethernet interface (while the back is facing you), but doubt that the choice of port matters. Here are my notes:

I logged in to cheshire-cat, plugged in a USB stick (PNY Attache'), and, after w
aiting about a minute, tried "add consult; attach-usb". Here is what I then got:
athena% attach-usb
Alert: attach-usb needs to run as root. Either "su" to root
before running attach-usb, or type the root password now:
Password:
Error: could not find any recently inserted usb drives.
athena%
However, dmesg clearly lists the following output:
<snip>

What should have happened:
The USB stick partition /dev/sdb1 should have mounted.
In the meantime, I suggested the following as a work-around:

Hi Joel,
I was able to reproduce the error you gave on an HP workstation in N42. We will
report the bug for you. For the interim, you may also try the following on a pub
lic HP workstation:
athena% tellme root (Tells you the root password.)
athena% su
Then, assuming that there are no other USB drives attached ("mount" with no argu
ments will tell you),
athena# mount -t vfat /dev/sdb1 /mnt/usb
When you are done, you should run
athena$ su
athena# umount /mnt/usb
Let us know if this does not work.
