gscanbus: resource temporarily unavaliable
Hi,
I recently bought a Sony MiniDV camcorder (DCR-HC44). This model has an
iLink output, so I bought an IEEE1394 host adapter, too. The adapter has
the chipset Agere FW323-6, which is reported as "working" on
www.linux1394.org.
Actually, the IEEE1394 card is working, but only when the camera is off!
When I turn it on, it shows on the display the icons the should mean the
camera is connecting via Firewire, but kino says there are no IEEE1394
devices, and testlibraw says something similar.
In particular, when the camera is turned on, gscanbus eternally repeats
this message: "Error while reading from IEEE1394: : Resource temporarily
unavailable". It immediately stops when camera is turned off.
Besides that, the only things that changes when the camera is turned on
are on testlibraw output (see below): absolutely nothing is logged
anywere when camera is turned on or off.
I'm running Debian Etch with its current kernel (2.6.18-5). I did not
install any software compiling source code.
Please note that I get exactly the same results with another adapter
that I borrowed from a friend of mine. This second adapter is based on
VIA VT6307, another chipset among those listed as supported on
www.linux1394.org.
I'm not going to buy another adapter, nor camera. What else
Here are some outputs and logs.
