D6000 BIOS A15 - USB over replicator issues
Problem:
Webcam does not work if connected to the APR, but does work if directly connected to the undocked laptop.
Also a scanner device that is not recognized (sometimes "insufficient power" warnings)
Also a USB stick that works fine on other PCs, fails if connected to this APR.
Please do not suggest that I update windowz drivers, or tweak windoze parameters, the OS is Linux.
Oh, well then, the problem must be the lack of Bill Gates on the machine.
No, the problems also happen with windoze as well.
None of the issues happens if the USB peripheral is directly connected to the undocked laptop.
Yes, this could be a one-off hardware defect, I have a contract call into My local Dell people.
Yes, I've swapped the Power supply, no I don't have a 2nd APR to test with.
so a few questions, if you please:
(this is more a matter of principle, rather than the actual need to get the USB working properly)
Is the APR (not a docking bay) USB circuit a purely passive device ? (just an electro-mechanical extender for the USB) ?
Is there firmware for the APR that one can upgrade ?
The D600/APR I have are perhaps a bit old, is there any way to determine if this might be a hardware revision issue ?
thanks for any information.

I am curious how you can get a powered USB hub "thru" the buggy USB ports on the APR.

Indeed, the APR is buggy. When I 1st tried the powered USB hub, it actually failed to initialize. looks dodgy...
Subsequent tests, the hub did come up properly, and the camera, when attached to the hub, was recognized, initialized properly, but resulted in the same error, which basically means the application send a command to the USB device (camera) and failed to get a response.
Dell support told me that the APR can put out max 250mA power, the camera lists as 160mA, so I removed all other USB devices (just a Dell mouse 100 mA), same results.
Does not appear to be purely a power issue.
Dell also informed me that the APR is more than just a copper bus-extender, and possibly requires some APR drivers (windoze only) to work properly. Which could mean that certain peripherals will never work on the buggy Dell USB structure, unless one submits to the naked emperor.
Overall, I just think the Dell APR is hmmm... junk... and I personally will probably not purchase another Dell (this is the 3rd that I have). Just when you think Dell is pushing quality, you find a hackaround architecture, and the weak answer from Dell "why aren't you running windows", and "oh well, I guess it doesn't work"
