MuxInterfacev2Receive expected sequence ..

Here's a strange one:

I set up an Ubuntu server to share a USB device to my Mac running Mavericks 10.9.2 and the VirtualHere.app.

Worked like a charm! So, so awesome.

In a heart beat I ordered a Raspberry Pi to make that the main sharing "machine" instead.

But with this one, there's no love. The Raspberry Hub and my iPod shows up under USB Hubs, but when I connect to it, nothing happens except my my console continually outputs the following lines:

05/03/14 20.58.36,143 com.apple.usbmuxd[47]: MuxInterfacev2Receive expected sequence 25 got 31 from 0x4-bc1cfec091994fc75c1cde43e0e4ce98fb091feb@0x1100000

Any ideas?

I've tried 3 different cables with an iPod 5th gen. (Lightning, iOS 7.1b5), iPad mini (Lightning, iOS 7.1b5), and an iPad 2nd gen. (30-pin iOS 6.0)

All through a powered hub. I've also tried both ports on the Raspberry Pi ..but sadly no luck. Same behavior. :(

I have debug log from VirtualHere.app I can mail to you if you're interested?

The VirtualHere.app occasionally crashes when I test, just as I plug in the device. The following is the output to the console and the resulting crash report. I wonder if that has any clues?

After the crash, I get a "The application "VirtualHere.app" cannot be opened. -600" error message. A reboot gets things back on track. (I read that Bonjour could cause some wackiness, so I've turned off Auto-find Hubs and manually put on the IP and port of the Pi.)

Edit: crashes don't occur when I plug in the device, but at the point where the app tries to connect to the device.

It'll be displayed as available in the tree, but then occasionally crashes when I right click and choose to connect to it.

Hi thebrew, I think i fixed the crash, could you download version 2.1.0. If it crashes again could you send me the crash report log to mail [at] virtualhere.com (mail[at]virtualhere[dot]com) that will now contain a detailed stack trace when using 2.1.0 of the client.

So far no crashes. :)

Still the same MuxInterfacev2Receive issue though. I've been troubleshooting a bit more, so here's my findings:

vhusbdpi for the latest Raspberry Pi (currently 3.10.33+ #654) works fine with every USB device I've tested (keyboard, mouse, BD-writer, hard disk USB interface). But any iOS device running version 6.0 or above produces the console log messages I pasted above. Sadly I don't have any iOS devices with iOS 5 but my iPod and iPhone 3G with iOS 4.6.1 works fine.

I don't know if 6.0 silently added the beginnings of the iOS 7 "Trust This Computer" dialog that pops up the first time you connect a new device, but I wonder if this could be at least part of the reason. Whenever I attach my device it asks me to trust it, when I tap "Trust" VirtualHere disconnects from it and it then shows up a second or two later, but reconnecting just shows the "Trust" dialog again. And so on.

As you said, it could be a Raspbian kernel issue, I just wanted to feed you some more info in case it could be related to vhusbdpi.

Is it just me experiencing this issue?

Thanks for the detailed feedback. I made a change to the threading in the osx driver, could download version 2.1.2 and see if that helps. Reboot your mac before running version 2.1.2 as it will need to upgrade the driver...

#10

OK good news is ive been able to reproduce the issue on my office test setup, havent found out why it is doing that yet, but at least i can use my usb hardware protocol sniffer...

#12

OK i got it working on my pi, indeed it is a bug in the latest raspbian, i dont know what it is but this seems to fix it:

1. Download an old raspbian image, i found one here
http://www.xs4all.nl/~sbp/rpi/2013-09-10-wheezy-raspbian-nox.zip

2. wget http://www.virtualhere.com/sites/default/files/usbserver/raspbian_wheez…

3. chmod +x ./vhusbdpin

4. sudo apt-get avahi-daemon avahi-client-dev

5. ./vhusbdpin -b

Then give it a try.

This is fantastic. Working! Thank you so much for your time. License bought in a heartbeat.

It doesn't even need an external hub when using a Retina iPad mini. :)

For other Mac users following along at home, here's a step-by-step guide:

* Download http://www.xs4all.nl/~sbp/rpi/2013-09-10-wheezy-raspbian-nox.zip and unzip the .img file.
* Insert the SD card you want to wipe and install to into your Mac.
* Open Terminal and run:
* "diskutil list" to see what the card has been mounted as. In this example it's: /dev/disk3
* "diskutil unmountDisk /dev/disk3" to take it offline. (Verify that it disappears from the Finder so you don't accidentally wipe the wrong drive..!)
* "sudo dd bs=1m if=
of=/dev/disk3". It'll ask for your super user password. Wait patiently as it transfers the 2 gigs. If you like watching paint dry, you can open Activity Monitor, click the "Disk" tab and filter on "dd" to see how long it's gotten in the process.
* "diskutil eject /dev/disk3" when it's done to eject the card safely.

Insert the card into your Raspberry Pi and connect the power.
Back to the Terminal on your Mac:

* "ssh pi@
" (If you don't know the IP, you can either check the DHCP clients on your router or you can type in "ifconfig" to see what eth0 says for "inet addr".
* The default password for user pi is: raspberry

In the remote session type:

* "passwd" to change the default password.

Install the service:

* "wget http://www.virtualhere.com/sites/default/files/usbserver/raspbian_wheez…"
* "chmod +x ./vhusbdpi"
* "sudo apt-get update"
* "sudo apt-get install avahi-daemon libavahi-client-dev libgtk2.0-0"
* "sudo mv vhusbdpi /usr/sbin"
* "wget http://www.virtualhere.com/sites/default/files/usbserver/scripts/vhusbd…"
* "sudo chmod +x ./vhusbdpi"
* "sudo mv vhusbdpi /etc/init.d"
* "sudo update-rc.d vhusbdpi defaults"
* "sudo reboot"

Boom. You have a remote USB port. :)
