Hi All:
Amy trying to write disks and have tried using xfbrn and Brasero and get the same error is my syslog:
| Code: | Aug 01 14:00:33 [kernel] [193833.714011] usb 2-1: reset SuperSpeed USB device number 2 using xhci_hcd

I've tried DVDs and CR-Rs, I get the same error.

it also borks the disk after the attempted write.
I can read from CDs and DVDs fine, its just the writing that does not work.
Any tips? Google-fu has failed on this one.
Cheers,
John

jserink,
I don't really believe the There is a spin motor, some electronics and a writing laser in there.
Put your entire USB device tree onto a pastebin site so we can look at how everything is connected.
I suspect a power issue as reading works but the higher power writing mode does not.
If you want to test run lsusb and rearrange your USB devices so that the DVD writer has a USB bus to itself.

As with the information available it looks like a HW not a SW problem. There seem to be two possibilities:
1) As NeddySeagoon wrote it might be a simple power supply problem. Your builtin SATA drive has a maximum power consumption of 1.5A for spin and seek. It's peek current but the voltage drop might confuse the USB-to-SATA converter already and force the RESET. The typical current is given with 150mA but this might well be higher in writing mode. Note that a standard USB2 port will deliver 500mA and USB3 900 mA - but this might still include a voltage drop (see comment above). Your drive seems to be this one.
So, you may want to try several USB ports on your PC, USB3 might be preferred - not for speed but for current capabilities.
2) The manufacturer of your unit tends to combine the housing with different brands and even used drives. So, you might be lucky with your pick - hopefully. I wouldn't spent much time after you have followed the advice from #1. If it doesn't help you may want to take a screw driver and check for the manufacturing date of your drive or any signs of use.
Good luck. |

Hi Guys:
Thanx for the info...bad news I think:
Without the drive connected:

With the Drive connected:

|__ Port 11: Dev 6, If 1, Class=Video, Driver=uvcvideo, 480M
|
it looks to be on its own. I confirmed this with lshw. Its on the second USB controller all by itself.
Looks like I'm out of luck. There is also no external power port to supply it from an external source which is too bad.
Cheers,
john

Or a Y-Cable.

Anyone who manage to get this DVD to play ?
I bought it believing I could play DVD with my new pi4, but all I get is a:
| Code: | | sr 5:0:0:0: Power-on or device reset occurred |
even on my ordinary computer, with a Y cable and a 3A usb-adapter

Ivar,
The Pi 4 will not power it.
I have a home made Y-cable, that is data only in one leg and power on the other.
The data leg plugs into the Pi, the power leg into a powered USB root hob.
Many commercial Y-cables do not split data and power that way. They are intended only to fool a laptop that it is powering several devices.
The Pi will not be fooled that way.
Try a powered USB hob plugged into the Pi and the DVD player plugged into the powered hub.

My Y-cable has only data in one of the 'legs', and that one goes to the pi/computer, the other goes to the 3A adapter.
But how much power can a little extern dvd-player use?
A 3A-adapter + the pi-adapter should be enough to boil potatoes and fry a steak with. 
I will try it through a powered usb-hub also (it hasn't arrived yet).

Ivar,
Your Y cable may have data and power in one log and power only in the other leg.
That connects the 3A USB charger and the Pi PSU to the Pi. This is where it gets complicated.
The two PSUs will not load share because they will have different output voltages. Due either to design or production tolerances.
What will happen is that the PSU with the higher output voltage will try to supply the whole load.
I'll leave you with that thought. Put simply, only one PSU will do anything.
Its actually more complex than that but its a reasonable top level summary.
Hence you need to be sure that the loads are separate when you use several PSUs around the same problem.

NeddySeagoon,
I didn't know commercial Y-cables have such a configuration. What are they made for, to drain power from USB port? What if external PS has a little higher voltage. It could potentially damage the USB port power circuits if it can supply up to 3 A or maybe even more.

I see.... and understand what could be trouble...
Thank you for the wisdom of powersupplies!
Will be back with a result when the usb-hub arrive!

Jaglover,
A (laptop) PC has a number of USB root hubs. One root hub usually appears as a pair of USB sockets. Its not always this simple but it will do for the explanation.
A USB1 or USB2 root hub can provide a maximum of 500mA for all connected downstream peripherals. For USB3 its 900mA
When the current limit is reached, the root hub is supposed to enforce it some way.
If I want to connect a bus powered device that requires more than the current limit of a single root hub, e.g. something with a spin motor, I theory, I can't.
Enter the Y-cab/e hack and all the USB power issues it causes. You connect one arm of each end of the top of the Y to different USB root hubs in an attempt to double the current limit.
Its not perfect but at the back end, its the same PSU providing all the power, so the voltages at the root hubs are the same.
The tracking and cable resistances all help with the load sharing, so it mostly works.
Users connecting both arms of the top of the Y to the same root hub don't bypass the current limit ...
Users that only have a single root hub may not know it ...
Its all a dirty hack. Equipment that is supplied with a Y cable is to be avoided.
For completness, USB root hubs do one of three things in the event of an over current condition.
1. Nothing at all, until the tracks on the motherboard are destroyed.
2. Shut down to root hub, so no bus powered devices work on that root hub.
3. Selective load shedding, so some devices work and others don't.
The Raspberry Pi is a bit of an oddball. It cannot provide even the 500mA/900mA spec limits for USB bus powered devices.
