1394 Firewire device drop off after sleep
I have an HP Slimline s3480a Desktop PC, attached to firewire M-Audio
Firewire 410 external sound card. Firewire is supplying the power to this device. Also running Microsoft (R) Windows (R) 6.00. 6001 Service Pack 1 Multiprocessor Free. All was working fine up until about 1 month ago. When the computer resumes from sleep my M-Audio firewire is no longer recognized. I need to then power cycle the PC (a warm reboot, by using shutdown-restart doesn't help) to be able to again use the M-Audio firewire 410. I have the latest M-Audio drivers installed hoping this would resolve the problem but hasn't helped. I've check for driver updates from HP's support and drivers update web site, none specific to firewire is available. TGhere were some recommenation for disabling the mouse and keyboard from sleep mode by configuring the device driver - but this options is not availabe for the firewire device or the M-Audio sound device. I noticed my 1394bus.sys driver has recently been updated just about the time this issue started to occur. Is it possible that this update driver is the root cause of the problem? Is there any way I can diagnose this issue so that I know what the root cause is? Here is the driver version 1394bus.sys 6.0.6001.18000 14/06/2008 Any ideas or solutions would be much appretiated! Kind Regards Jim

Just like to add, these are the "power data" section for the m-audio device,
might mean something to someone, (this is taken after a power cycle and the m-audio now available)... Current power state: D0 Power capabilities: 00000009 PDCAP_D0_SUPPORTED PDCAP_D3_SUPPORTED Power state mappings: S0 - D0 S1 - D3 S2 - D3 S3 - D3 S4 - D3 S5 - D3 "JimmyT" wrote: I have an HP Slimline s3480a Desktop PC, attached to firewire M-Audio Firewire 410 external sound card.
