Re: USB Pen drive

Hi Folks,

I was finally able to borrow the USB stick for a little more fooling
around, and this rather long email contains the results.

To cut a long story short, no, it isn't working yet. I'd like to fool
around a little more and get it to work, though, and I'd appreciate
any help I get. Before I go further, I'd like to say Thanks a Lot to
everybody who took time to reply :)

On my box, running DF 1.5.4-Preview, the USB stick is still not
recognized. What's more, kldloading ehci.ko results in my USB keyboard
freezing :)

This is what dmesg has to say about my USB controller:

-- snip --

uhci0: <Intel 82801FB (ICH6) USB controller USB-A> port 0xff80-0xff9f
irq 9 at device 29.0 on pci0
usb0: <Intel 82801FB (ICH6) USB controller USB-A> on uhci0
usb0: USB revision 1.0

-- snip --

On a box running DF 1.5.4-DEVELOPMENT, the USB stick is recognized.
However, I wasn't able to see any filesystem on the stick. (I tried
the same stick under NetBSD on the same machine, it worked just fine).
This is what I got:

As we can see, disklabel doesn't recognize anything on the stick.
Under NetBSD, however, this is what disklabel has to say:

Now, I'd like to fool around some more and get this thing working, but
I have no idea what to do next. Any pointers from anybody, please?

Thanks,
Karthik.
