USB, Digicam, Trouble

Shadewalker · 02-16-2005, 01:45 PM

Now, where to start...

I can't seem to connect my digicam, a Canon Powershot A80. It HAS worked before, so I assume the problem is solvable.

I run:

Slackware 10.1
Kernel 2.6.10

My portable MP3 player works fine. I plug it in, a message is spit out in dmesg, an entry appears in /dev (sda*), and I can mount it. Fine, just fine.

Now, plugging in the Canon toy is a whole different story. Let's take a look in dmesg:

Code:

usb 2-2: new full speed USB device using ohci_hcd and address 3

... but there is no sda* in /dev/.

Code:

thomas@nightshadow:/$ cat /proc/bus/usb/devices

Seems it shows up!

And here:

Code:

root@nightshadow:/proc/bus# lsusb
Bus 003 Device 001: ID 0000:0000
Bus 002 Device 003: ID 04a9:309a Canon, Inc. PowerShot A80
Bus 002 Device 001: ID 0000:0000
Bus 001 Device 001: ID 0000:0000

I've Googled for a while, and found out that, since USB devices somehow "go through" (?) SCSI (this requires the generic SCSI and SCSI Disk drivers in the kernel), the device should also appear in /proc/scsi/scsi.

Code:

thomas@nightshadow:/proc/scsi$ cat scsi
Attached devices:

Nothing.

After more Googling, I found out about something called "gphoto2". Let's take a look:

Code:

thomas@nightshadow:/proc/bus$ gphoto2 --auto-detect
Model                          Port
----------------------------------------------------------
Canon PowerShot A80 (normal mode) usb:

Aha!

Let's try something else:

Code:

thomas@nightshadow:/proc/bus$ gphoto2 --auto-detect -P
Model                          Port
----------------------------------------------------------
Canon PowerShot A80 (normal mode) usb:

*** Error ***

And in dmesg:

Code:

usb 2-2: usbfs: interface 0 claimed while 'gphoto2' sets config #1
usb 2-2: usbfs: USBDEVFS_BULK failed ep 0x81 len 4 ret -75

... and that's about how far I've come. I've tried to be as specific as I can - bear with me if it's not sufficient. Any help is appreciated - thanks in advance!

It looks like usbfs is barfing, that's a kernel issue. Offhand it doesn't look like anything wrong in userland, so I figure a different kernel with usbfs compiled out and it should do the normal usb emulated as scsi direct access and skip that libusb nuttiness. Also, might want to see if you can get any mileage out of the scsi rescan script that slackware has started to ship:

rescan-scsi-bus

Cheers,

Finegan

Shadewalker · 02-17-2005, 08:47 AM

finegan,

Thanks for the reply. Running the script didn't show reveals nothing usable - no devices detected. If no other suggestions show up, I might try a different kernel (even 2.4) as a last resort.

Cheers.

finegan · 02-17-2005, 09:36 AM

Its kernel. If you're feeling spunky, a hand compile of 2.6.10 and removing that usbfs option under the USB section under Device Drivers, will sort the problem.... or should rather.

Cheers,

Finegan

Shadewalker · 02-17-2005, 11:22 AM

No luck. Unless we aren't talking about the same 'usbfs' ?

Quote:

USB device filesystem (USB_DEVICEFS)

That is what I disabled.

Hi,

I'd be tempted to try the default Slack 10.1 2.4 series kernel - 2.4.29 I think. You should find it right there on your slack install cd.

Personally, although I'm sure this is just me, I've had real hassle with usb anything with 2.6.x kernels in the past. But with the 2.4 series, my usb camera works perfectly with my laptop and this machine, and my printer works great with cups (after foomatic-beta messiness mind) so I'd be tempted to give that a try and see what happens.

Cheers,

Steve

depi · 07-04-2005, 03:43 AM

Hi. I have this problem too, I use Slckware-current and the 2.6.12.1 kernel, i tryied it with the 2.4.2 slackware kernel, but there was this problem too.so i now really dont know what to do, if i may add older kernel 2.6 or older program gphoto2, because i used the new release from 26th of june 2005.

Anyone has this problem again? I really dont know what to do.

depi · 07-04-2005, 03:55 AM

Okay I write here some informations about my configuration and outputs.

So when I connect the camera to the PC from the dmesg I get:

Code:

usb 2-2: new full speed USB device using uhci_hcd and address 2

when I try to:# gphoto2 --auto-detect I get:

Code:

root@depi:/home/depi# gphoto2 --auto-detect
Model                          Port
----------------------------------------------------------
Canon PowerShot S1 IS (normal mode) usb:

So now I try to:# gphoto2 --summary and I get:

Code:

root@depi:/home/depi# gphoto2 --summary
Detected a 'Canon:PowerShot S1 IS (normal mode)'.

*** Error ***
lock keys failed.
*** Error (-114: 'OS error in camera communication') ***

and from: gphoto2 --debug --summary I get this: http://pokusy.depi.sk/linux/gphoto2-summary-debug.txt

I hope that will helps.

Hello,

I had the same problem with getting pics from my Ricoh RDC-4200 Digicam (serial port) with gphoto2 on a Debian System. Then I tried to change the IRQ's, but it didn't work, just the time I could download changed a little bit. I solved the problem by stopping gdm and logging into tty1. So after stopping the X- Server it worked. In fact I've no clue why... I just wanted to post that, because I searched for a solution a long time and found nothing...

Greets,

Markus

buaku · 08-09-2005, 05:58 PM

Have y'all tried running gphoto2 as root?
I could run it ok as root, but as a normal user it dind't work.

It was a permissions problem for me, I found a link to set up a hotplug script to sort things out, I just have to remember where the link is.
