 |
|
Hi, I reconnected HDD from RPI to BPI-M2-Ultra USB (tried powered HUB also) and when reading it is OK, but writes after some time ends with errors.
RPI OK, other gentoo machines OK too - even on same USB HUB.
Here are the log entries:
| Code: | Sep 2 21:55:40 bpi1 kernel: usb 2-1: reset high-speed USB device number 2 using sunxi-ehci

after that sdb disappears and becomes sdd (sdc is WD external HDD which is OK - connected to powered USB HUB. This WD is taking more power than problematic disk)

Could someone help me understand what's going on here?
Could newest kernel version from BPI help?
Thanks in advance!

I have a technical question:
Is it possible that it's a problem of grounding?
Since there is no connection to ground is isolation working?
Doesn't USB cables tend to interference or noise then? |

DeIM,
USB 2 is only specified to provide 500mA for all connected devices.
Most USB hard drives need more that that for the spin motor alone.
What happens when you try to draw more that 500mA varies depending on the device providing the power, options are,
1, It destroys the tracks on the motherboard as there is no overcurrent protection.
2. The overloaded bus still works
3. The bus controller powers down some devices to get the load under 500mA
4. The bus controller shuts down the USB root hub.
This is why many bus powered USB HDD are provided with a Y cable, so that they can be powered from two different USB root hubs.
Its not ideal but it is at least, honest.
I don't think is a USB cable noise problem, its probably PSU related.
Many USB phone chargers,marked as 5v, used for powering SBCs, only provide 4.7v to suit Lithium batteries. That 300mv matters, as the voltage drops further when the PSU is working hard. At 4.5v normal operation is not expected.

Seems to be solved now - I replaced cable BPI <--> HUB. The cable was really bad in random situations.
Just as a tip - Since HUB is powered, I removed +5V pin on USB connector. It seemed to be the error when I tried to replace cable first time (but didn't verify).
I've tried two disks at once with bonnie++ tests and no error so far.
Thanks everyone who read this and thought about reasons, esp. thanks to NeddySeagoon |
