Canon EOS 300D not working in -HEAD with gphoto 2.5.5

[Matthias Apitz]

Hello,

I have the above cam attached to an Acer C720 Chromebook running HEAD
from January. gphoto can not read from the cam, it is detecting the name
of the cam as EOS 300D but can not read bytes from USB. With truss the
situation looks like this:

...
open("/dev/ugen0.3",O_RDWR,00)                   = 5 (0x5)
open("/dev/ugen0.3",O_RDWR,00)                   = 6 (0x6)
ioctl(6,USB_GET_PLUGTIME,0xbfbf9f6c)             = 0 (0x0)
ioctl(6,USB_FS_INIT,0xbfbf9f70)                  = 0 (0x0)
write(4,"\0",1)                                  = 1 (0x1)
ioctl(5,USB_IFACE_DRIVER_ACTIVE,0xbfbfa008)      ERR#6 'Device not configured'
write(2,"Detected a 'Canon:EOS 300D (norm"...,43) = 43 (0x2b)
ioctl(5,USB_DO_REQUEST,0xbfbf9050)               = 0 (0x0)
write(2,"\n",1)                                  = 1 (0x1)
write(2,"*** Error ***              \n",28)      = 28 (0x1c)
write(2,"Could not establish initial cont"...,48) = 48 (0x30)

In messages on cam attach it says:

Feb  8 09:41:06 c720-r276659 kernel: ugen0.3: <Canon Inc.> at usbus0
Feb  8 09:41:06 c720-r276659 root: Unknown USB device: vendor 0x04a9 product 0x3084 bus uhub0

Any ideas?

La referencia de la Duma a la anexión de la RDA, en este caso al contrario con la Crimlía sin
referéndum, no solamente tiene gracia sino da en el blanco.-
