Anderton Posted June 18, 2004 Share Posted June 18, 2004 This was sent to me by M-Audio, and is being published here as a public service. --Craig ------------------------------------------------ Reports have come to our attention of isolated problems when hot-plugging IEEE 1394 (aka FireWire) devices. (Hot-plugging refers to making 1394/FireWire connections when one or more of the devicesincluding the computeris on.) When hot-plugging, there are rare occurrences where either the FireWire peripheral or the FireWire port on the host computer is rendered permanently inoperable. While M-Audio products adhere rigidly to the FireWire industry standard and pass stringent internal testing, the possibility remains that hot-plugging your M-Audio FireWire interface with some computers may result in the type of problem described here. We strongly encourage you to protect your equipment by refraining from hot-plugging any bus-powered FireWire device, including the M-Audio family of FireWire products. Connect your FireWire device while both the computer and FireWire device are powered off. Power on the FireWire device, then turn the computer on last. If you are using bus power (systems with IEEE1394 6-pin connectors) make sure you make the cable connection first, then turn the FireWire device power switch on, and turn the computer system on last. M-Audio is being proactive in investigating any issues that may adversely affect our customers. Please consult the Knowledge Base in the Support section at www.m-audio.com for updates on this important issue. In case your M-Audio FireWire device is not detected by your computer on startup, try one or more of the following troubleshooting steps instead of hotplugging it: 1. Turn your M-Audio FireWire device off, wait 30 seconds then power it on. 2. Put your computer into hibernation mode, wait 30 seconds then reactivate it. 3. Restart the computer (dont turn it off) while the M-Audio FireWire device remains connected and powered on.

Alndln Posted June 18, 2004 Share Posted June 18, 2004 Thanks for the heads up.Even though iEE1394 claimed hot-plugging ability,I could never bring myself to test Murphy's law so I never even tried it.Like a nerd,I alway's shut down before attaching anything.I guess it paid off this time.

zeronyne Posted June 18, 2004 Share Posted June 18, 2004 They are not explicit enough...are they saying that ALL Firewire devices exhibit this issue? I don't like that they are implying something that they haven't stated they've researched outside their own product line. Hot swapping is one of the integral functions of Firewire for me. It would be like having a car with no reverse gear. "For instance" is not proof. Link to comment Share on other sites More sharing options...
spokenward Posted June 18, 2004 Share Posted June 18, 2004 I have been hearing this more and more frequently. Did they suggest what part or parts are failing when a hot-plugging goes wrong? I think the caution makes sense for bus-powered devices. (and having lived in Minneapolis and Chicago in the winter time I learned "positive to positive and negative to ground". oh yeah, and wear eye protection.)

Geoff Grace Posted June 18, 2004 Share Posted June 18, 2004 Hmm... I also wonder about other hot-pluggable specs such as USB. My cursor sometimes freezes, for instance, when I plug my USB printer in. Unplugging and replugging my USB keyboard or mouse usually fixes the problem.

Philip OKeefe Posted June 18, 2004 Share Posted June 18, 2004 I just hot plugged something last night, and it's not even mine. Worked fine though. Link to comment Share on other sites More sharing options...
Alon Posted June 18, 2004 Share Posted June 18, 2004 Hey, remember - This is just for bus powered Firewire stuff. I hotplug firewire drives (external powered) all the time, and nothing ever happens. alon . Link to comment Share on other sites More sharing options...
ITGITC Posted June 18, 2004 Share Posted June 18, 2004 Folks, Was there ever a final determination which is better for audio: Firewire or USB2.0? I had heard that there were some 'hiccups' with USB 2.0. However M-Audio uses USB in their products. Also, my laptop has USB 1.1; not USB 2.0 . Is USB 1.1 fast enough to use with audio interfaces? Again, I would think that it is since many manufacturers seem to be using it. What's the latest on this... anybody? Is There Gas In The Car?

where02190 Posted June 18, 2004 Share Posted June 18, 2004 USB1.1 is capable of doing 2 i/o at 24/48, or one way (record or playback, but not both simultainiously) at 96K. such devoces include the Protools M-box and Mackie Spike. Hope this is helpful. NP Recording Studios Analog approach to digital recording. Link to comment Share on other sites More sharing options...
RABid Posted June 18, 2004 Share Posted June 18, 2004 Thanks for the warning Craig. I just recently started using Firewire HDs at work, home and for music. Also just started using an iPod which is charged by Firewire power. As for the USB question, consider getting an interface card like this one for your laptop. I added a Firewire card to mine recently. The one I chose uses a dongle cable with the jacks. I had to go with the dongle type because I already had a sound card in the other slot that has an oversize end for connections. You cannot fit two oversized cards into the two available slots at the same time. Robert This post edited for speling. Link to comment Share on other sites More sharing options...
Gus Lozada Posted June 18, 2004 Share Posted June 18, 2004 As one of many users around here, I have "hot-plugged" my stuff lots of times without a problem. That was actually my standard way to work with a FW device from my company. However as the message sent to Craig and all of our users, we have had reports talking about -ours and other manufacturers- problems while hotplugging a FireWire device. Given the circumstances, we had to send this word of advise to all of our users.

phaeton Posted June 18, 2004 Share Posted June 18, 2004 Also note that hot-plugging arbitrary devices such as groupies can cause damage to your peripheral and cause a medical condition known as FireWire. We strongly encourage you to protect your equipment by refraining from hot-plugging any bus-powered device, even if it is your own tour bus. Dr. Seuss: The Original White Rapper . WWND?

Kaptain Karl Posted June 18, 2004 Share Posted June 18, 2004 It has to do with how manufacturers of FW devices and periphials deal with over-current protection.There are FW cards and hubs that do have over-current protection and is obviously a wise thing to look for. Just do a search on Google 'firewire over-current protection' "When I look at the smiles on all the children's faces,,...I just know they're about to jab me with something." -Homer J.

Anderton Posted June 19, 2004 Author Share Posted June 19, 2004 FireWire hard drives and USB2/FireWire combo devices were mentioned in the cover letter sent by M-Audio, it's not just referring to their bus-powered gear.

cerumen Posted June 19, 2004 Share Posted June 19, 2004 I just lost about 250 gigs of info the other day with a hard drive attached via firewire in a lian external case. And it happened after at least 10 on/off's..... in a 1/2 hour's time. Link to comment Share on other sites More sharing options...
