2- my Dell laptop has a 4-pin firewire output and was wondering if there are
any issues with using a 4 pin cable for a 6 pin I/O other than not supplying
power?
I know I have to supply power to the box since a 4-pin 1394 connector
doesn't carry DC power.
There should be no issues. The 6-pin connector is literally the 4-pin
connector signals (2 out, 2 in) with 2 power wires. There is no
difference in the IEEE-1394A specs for either connector and, in my
experience, the 4-pin has always worked for me.
OK thanks for the info! :)
The biggest issue with 1394 on Linux is the 1394 controller in the PC.
You might look around for evidence that your specific hardware (the
chip inside - not the laptop) is well supported. (I.e - TI is, others
vary) Stefan Richter in the 1394 user list is a great resource. lspci
is your friend.
yeah I did a lspci and found:
09:01.0 FireWire (IEEE 1394): Ricoh Co Ltd R5C832 IEEE 1394 Controller
(rev 05)
-- also --
sudo lshw | grep 1394
description: FireWire (IEEE 1394)
product: R5C832 IEEE 1394 Controller
configuration: driver=ohci1394 latency=32 maxlatency=4
mingnt=2 module=ohci1394
Ricoh chipets are, IIRC, the ones with extreme nonworkingness. Though it may depend on which rev, I dunno.
I had one, and nothing worked. I had to get an ExpressCard with a TI chipset, and that one worked.
which ExpressCard I/O did you buy?
