DENEB - Error Log Help

[Kernel]

I'm not sure if this has been happening since I installed the DENEB last week or if it just started happening after I flashed the firmware to 11, but my external DVD-RW is sometimes not being recognized and there are errors like this (and other not exact but similar) in the log

5-hub.class: CLEAR_PORT_FEATURE (C_PORT_CONNECTION) failed": packed overflow (7)

I've tried restarting the stack through Trident but that appears to work spotty as well.

I also tried reflashing back to 9 (which I assume is what it was at when I got it) but the issue persists even then.  The LEDs light fine for power and ZII mode.

I have an A3000D with 2 Chip/16 Fast and a fresh load of 3.1 and 3.9 on separate partitions and both exhibit the same behavior.

I'm going to try a powered hub but I'm curious if this sounds related to power consumpotion and I just didn't notice it at first or if this could be something else like card issues.

Just a thought, but have you also updated to the latest versions of Poseidon and Luciferin (currently v4.1)?

They're available here:

Well, I haven't checked them yet however I did pickup a powered USB hub and it appears everything is fine now.  Every time I boot, cold or warm, the CD drive is there and no errors logged now.

I did get a few stalls at boot during my preliminary tests but I believe I read somewhere someone said they found that issue happens with FLASH attached at boot and when I unplugged the FLASH, it booted.  Sometimes it boots fine with the FLASH though.

We'll see what happens - only time will tell.

I've read a few times that a powered USB hub is highly recommended due to the limited power output from the USB ports.  I've never had an issue with my USB-CDRW, but then it has a power supply the size of a brick.

Well, it's even worse... I had severe problems with one of my test setups here, which turned out to be a phenomenon of the PSU aging. I had 4.8V on Zorro III, which is already hard on the limit, which went down to 4.3V with a fully loaded Prometheus board. This made the machine going weird.

On USB you have a power budget for distributing "+5V" to connected devices.
This budget assumes that you really have 5V to distribute, not 4.7V. In the end, when a device draws much power (like CDROMs) you may end up in a mess as the voltage goes below the limits.

A powered USB hub is highly recommended in such situations, as well as checking the PSU status with a voltmeter from time to time. An original Commodore PSU (like mine) get to its limits with a PicassoIV, CSPPC, 128MB memory, floppy, one UW SCSI drive, DENEB, Prometheus (including a Voodoo3 and some other cards) :-)
