which ExpressCard I/O did you buy?On Tue, Nov 30, 2010 at 09:38:09AM -0800, Kim Cascone wrote:Mark Knecht wrote:On Tue, Nov 30, 2010 at 8:20 AM, Kim Cascone <kim@email-addr-hidden> wrote: <SNIP>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=ohci1394Ricoh 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.
