[gentoo-user] Mounting a usb device

[dhk]

I have a wireless hand held scanner that is temporary connected with a
usb cable.  I would like to embed Gentoo on it, but I don't know the
mount.  How can I find the device?

Bus 005 Device 004: ID 05e0:2000 Symbol Technologies

What do I do at this point to communicate with the device?

Thanks,
dave

Are you sure the device should appear as a mass storage device? That  
appears to be what you're expecting, but I don't find that clear at all.

No, I'm not sure how the device should appear.  However, I thought it
should look like any other disk or usb stick since it currently has a
Microsoft CE on it, which I want to change to Gentoo.

I googled a bit and it appears to be seen as a keyboard device.  I
googled for "05e0:2000 Symbol Technologies" with no quotes tho.  I
thought maybe I was finding the wrong device.

I'm still not sure what to do with this, but I'll see if any of these
Google links help.  Thanks.

I don't think that's a reasonable conclusion _at all_.

If the scanner plugs into a Windows PC and appears as a disk drive  
then, sure, I'd expect to be able to treat it the same under Linux.  
But, assuming it plugs into a Windows PC at all, it's more likely that  
the manufacturer's software (which you'll need on the PC anyway, to  
handle barcode & stock-control data?) talks to it over in some  
proprietary-over-serial format.

Finally, can you even install Linux on this scanner? Chances are its  
processor is ARM - Linux will run on that architecture, but you won't  
be able to chroot in from your x86 box & install GRUB.

Chances are that this scanner is some kind of rebadged HP iPaq or  
something, onto which Linux has been / can be cludged onto, but you  
seem to be making a lot of assumptions ahead of time.

I done have a Windows box so I don't know how it looks on that.
However, I already build the arm cross compiler and have a kernel to
install on it, the only thing is I don't know how to reach it.  Now I
just want to know how to get the kernel to the device.  This may be a
bigger project than I thought.

Thanks.

Having managed to cross-compile the kernel is a pretty good start. I  
couldn't do that much.

But you need to determine stuff like how the bootloader works on this  
device.

As I said, chances are that the device is not completely unique. If it  
is simply a rebadged HP iPaq or something then efforts (at the very  
least) to install Linux on it will surely be documented. First thing  
to do is learn all you can about the hardware.

Hi,
I have no clues about cross compiling and bootloaders other than grub
(ok, maybe lilo) but if you want to determine if that device is seen
as a storage device why don't you just plug it in and have a look at
dmesg?
when I plug a usb key on my machine i see something like this:

this tells me it's a storage device and the associated evice file is
/dev/sdb1 so i know where to find it...

I don't think that is possible...
