Topic: Raspberry pi usb device limitation? - page 3. (Read 15051 times)
Tried every release. Nothing works for me ;(
i have a pi and thought it would make a decent miner base......
But its not!
The Pi in its current state is a real bitch when it comes to USB connections. I hardly get a single Ztex board working there for a few hours. Then out of no reason the pi looses the device (including the hub) or freezes .....
A hard reset is then necessary to get it working again:/

Hi BR0KK,
Have you tried Raspbian "wheezy", the new recommended Debian based distribution optimized for RPi?
It seems more stable than Debian "squeeze", mining with BTCMiner on RPi for more than 1 days without hang is a new record to me
I uploaded a version of BTCMiner with USB libraries compiled on Raspbian:
Latest released version: https://www.dropbox.com/s/qc1fcgy18dp7nf8/ZtexBTCMiner-120703-raspbian.jar
Test version: https://www.dropbox.com/s/i3boafmrvp5l886/ZtexBTCMiner-121017-raspbian.jar
snipped the vc++ power from the USB connector on the board.
This way you will indeed not blow up the fuse but also prevents current leaked back into the board from the USB powered hub which will lead to crashes...
Why not just snip it in the USB cord? This way you will indeed not blow up the fuse but also prevents current leaked back into the board from the USB powered hub which will lead to crashes...
New ones have no fuses. I use a powered hub and 5v 1000 ma
I have no problem as I said earlier one it got past the bugs of xbmx5

Are you saying you snipped the vcc power going from the powered hub so you don't blow the fuse?
The USB problem is related to all USB devices.
For me removing the vc++ power from the USB and using seperate (USB powered hub) power adaptor fixed it.
Also; the Raspberry pi itself needs a good stable power supply or the board will crash random, especially under high load...

Putty does not work, I am sure it can be fixed easily.
Eternal bootloop-says "relax xbmc will resume" does not. Hit escape and logged in as pi , raspberry.
Unplugged usb devices and so on.
How I fixed bootloop- new ip address for some odd reason fixed it.
Text on the side of the screen when playing a movie in the black bars. Fixed it by doing video calibration(don't really understand why that fixed it either).
Double press error, booted up with mce keyboard plugged in. Ir receiver, no usb keyboard.

Got it all worked out, working fine now.
This was more of a challenge than xbmc 4

What did you figure out? Want to make sure I'm ready when mine comes in.

keyboard double press bug?
I haven't had this problem at all, can you elaborate?

It's caused by the USB issues, talked about earlier in the thread, you may not notice it until the thing gets busy and starts queuing requests >1ms.
Giving the USB processes realtime priority on the CPU, and everything else a lower priority, is probably the best solution they can come up with for this mess.
Got it yesterday. Got my mpeg2 lic today.
A little bit of trouble with xbmc 5,but I got the nightly build installed

i get mine tomorrow at work, hope ups shows up early.
I put my sd card in my wallet so it is with me at all times! just have to a find a hdmi
My New 512 does not suffer from lan bug

How long have you had your 512? Are you mining with it? I'm still hopeful I'll still be able to use mine with my singles.

I missed the early orders for the 512, I am on the email notify list.

the USB is not a broadcom part that is bought in
Splitting hairs, if it's Broadcom's SoC (System on a Chip) it's their problem for putting it in there.If there's a fundamental problem with the USB people need to be made aware of it before purchase
and not sent on a wild goose chase to change their power supply after purchase.
(A typical ploy one could use to run out the consumers right to return goods under distance selling regulations).
For some people USB may not be critical to their application, and still buy it, but for Bitcoin mining it is.
Pi need to point out the USB flaws near the "buy" button so consumers are not mislead.
I'm on the fence with these issues.
On one side:
Most uses for the Pi aren't too power intensive. My initial ideas for a use are like others (XMBC or stuff with the GPIO ports)
On the other:
If they state certain specs, friggen deliver to those standards!

lol Raspberry Pi banned the guy for pointing out the faults with Broadcom's USB.

Bid odd that a charity would not take criticism well (so I dug deeper!)...
...well it becomes clear when you realise the project co-founder is employed by Broadcom!

Come on! How is that for a conflict of interest! No wonder it uses problematic Broadcom parts!

all forums will have the troll issues and the more people you get the more of a problem it is
No fix for me.. Still drops. It's okay though xbmc still is awesome
Got a email, new 512 shipped from element 14
