I am hoping to get an IBM Thinkpad R51 from the insurance as it's about equivalent to the Dell. I understand that Thinkpads are pretty compatible with Linux and wondered if any of you have experience of this particular model?
Barry- if it is any encouragement to you, I've managed to get a dual-boot of Debian/XP working fairly well on my Thinkpad T22 and I represent very much the tail end of the technical distribution in this group. Two essential resources are http://www.linux-laptop.net/: they have several pages specific to the R51. This site was what helped me get my X-config files sorted out eventually. Then for your internal modem there is http://www.linmodems.org/- a very friendly place from where I found the right driver to download and get dial-up working. Good luck and enjoy!

My computer has 2 USB ports which connect to a mouse and a printer. Both work. If I connect my camera (Olympus E10) via the supplied USB cable, in place of the printer, I get no reaction from the system at all even with the usb-storage module loaded as I gather that is the one required. If I then disconnect the camera and plug in the printer lead the printer is then registered by the system. I've tried connecting the camera and then switching it on and I've tried switching it on first and then plugging in the USB cable with no reaction from the system at all. Usually the last entry in the logs is the usb-storage module being registered. Incidentally it won't react to my scanner either if I connect that via USB instead of the SCSI connection. Debian Testing with 2.4.27 kernel. Any ideas please? Thanks to Rob Grant for the web links regarding the Thinkpad R51.

It could be that the fact that you already connected the printer to the USB port left some of the modules in place when you unplugged it and plugged in the camera (or the scanner). I had a very similar problem with my Red Hat 9 (kernel 2.4.20-8). I'd been plugging in a USB memory stick and unplugging it with bi problems. Then I got a USB camera, and after the first use the stick no longer worked. I suggest you experiment a bit, along the lines of: 1. Reboot machine, with nothing plugged in (except mouse if you need it). Do 'lsmod' and note the output. Is there a /proc/scsi/scsi ? (there shouldn't be). 2. Plug in printer. Do 'lsmod' and note differences from (1). Do 'cat /proc/scsi/scsi' and also look into what's in /proc/scsi/usb-storage-* 3. Reboot as at (1). Plug in camera. Does it work? Do 'lsmod' and again note differences from (1) and (2). Likewise for what's under /proc/scsi as in (2). And so on similar. Basically, start with a clean slate and change one thing at a time. Try combinations. Just find out what goes on with modules when you plug things into the USB port. What the above sort of thing lead me to is that, when I use the stick or the camera, I mount it with mount /flash where /flash is a directory on which I mount /dev/sd1 (which is where the stick or the camera is seen after being plugged in, and /flash is an entry I have made in /etc/fstab). After using the stick or the camera, I clean the slate with umount /flash rmmod sd_mod usb-storage scsi_mod which removes the three modules that are brought in when USB storage is plugged in (the problem in my case was that while both the camera and the stick are USB storage, the entries in /proc/scsi/scsi which either creates when plugged in are left in place when it is unplugged, and whichever one it is is incompatible with the other. Removing the modules as above erases the entries in /proc/scsi/scsi and cleans the slate for whatever gets plugged in next). This is just a hint -- the above worked for me, but your problem may be different!

It might sound funny, but you are turning the camera on once connected, aren't you? If nothing is showing up in /var/messages then hopefully Ted's hints will help. Good luck! Tim.

IME the act of plugging it in should turn it on.

Have you tried usbview - USB device viewer it gives some useful information, on the usb devices connected regards owen S

I've tried it both ways - no reaction.

Because I want Debian Testing and if I try to use a 2.6 kernel on this machine I have to wait 2 - 3 minutes before it starts to boot. I've seen others report this problem but have not yet seen any suggested solution so I'm sticking with 2.4 kernels. I do have Hotplug but udev requires a 2.6 kernel.

I've tried the KDE info viewer which lists USB devices. The camera doesn't show.
I suggest you experiment a bit, along the lines of: <snip> Is there a /proc/scsi/scsi ? (there shouldn't be).
Why shouldn't there be? I do have a SCSI hard drive and a SCSI tape drive. SCSI disc support is built into the kernel i.e. not a module. I have tried experimenting by unloading all modules and then loading the mouse modules only followed by usb-storage to no avail. Having searched on the web I see that the E10 is supported as a USB Storage device and that, once the usb-storage module is loaded, it should register with the system but it doesn't. Hence my post here. I'm moderately baffled. Barry Samuels http://www.beenthere-donethat.org.uk The Unofficial Guide to Great Britain

Just a thought, if you can boot 2.6 on this machine why not just try it to see what happens? In the dim distant past I had quite a few problems with usb support using 2.4 which were fixed in 2.6 although 2.4 has come quite some way since then.

First a big thank you to all who tried to help. Now for the embarrassing bit! It now works! In the camera manual there is a short section on connecting to a computer. It doesn't say an awful lot except to assume that you will be using their own software (Windows). On the camera main control knob the symbols are divided into two sections - one for taking photographs and one for viewing photographs. I had assumed that the first symbol for viewing was the one to use. The second one is for printing and there was a third. I looked that one up in the manual and it said 'Settings/Connection menu'. Selecting that setting and pressing the menu button gave me a menu but no connection options. I decided to try connect with that setting selected and - bingo! There is no mention of that setting in the 'Connecting to a computer' section. Ah well - one lives and learns. Sorry about the false alarm.
