Maybe you want also to read http://www.beyondlogic.org/usbnutshell/usb1.shtml ?

In VUSB communication via host often is done by just using the control endpoint - the endpoint also responsible for communication
device descriptor and strings (vendor, type, serial ...) to the host.

For tinyUSBboard I prepared some VUSB template, some time ago.
You can find it as "VUSB skeleton/example with corresponding linux, windows (delphi) and platform independent GTK libusb program"

Has there been any progress on this. To get it working again requires a restart. just quitting the app isn't good enough. The functions affected are the two main functions I use Launchbar for.

Basic setup for tethered laptop to prevent huge data bills

A friend wants me to help set up his new MBP, which he will regularly use tethered to his iPhone as well as on his home WiFi network.

Exceeding data limits on mobile contracts is very costly in Australia. Little Snitch sounds like the easiest way to stop this (especially with auto profile switching), but I can't find much in the way of guides for non-power users about how to set it up. To be very clear: I'm not interested if Little Snitch can monitor every piece of data going in and out - I just want to ensure there aren't any unexpected big transfers whilst connected to his iPhone's Personal Hotspot.

I want his computer to function as normal when connected to any WiFi network except on nominated networks such as his iPhone, where I want to ensure that nothing unexpected causes a big download (e.g., system updates, automatic app updates, iTunes Match, etc, etc). Minimising pop ups in both situations is absolutely critical, otherwise he'll just uninstall it.

In his day-to-day work he mainly uses Dropbox, Safari (including Gmail), possible Evernote and Office apps. At home he uses MOG, Transmission, and no doubt quite a few other apps that he won't need when tethered to his phone.

Can anyone point me to a good basic guide, or provide an overview of how to approach setting this up?

Bonus points: for my own interest (possibly going to get a MBP pro as a supplement to my iMac workhorse) any advice on setting LS up to deal with Dropbox where you want to be able to access any specific file that you need, but don't want to unwittingly sync enormous Photoshop files added by a third party to a shared folder. i.e. basically how the iOS dropbox app functions, not how the OSX one does.

Well... nice to know in advance that "support" here is pretty much NON-EXISTENT. Seeing how many threads have ZERO responses and how many of the actual responses are even from someone Objective Development... NOT.

I knew nothing of usb and had very little firmware programming experience when I started on v-usb. I only needed two things, 1) example code 2) this form.

Similar here. I've found the guides hopelessly disorganized, presenting random details and commentary before the reader even understands the overall structure. Along the lines of example code being a good teacher, I'd love to see a log of an actual USB session for say a keyboard, describing each USB event, and what v-usb does internally to respond. Not a tiny snapshot of it, but the whole session, so one can see how it all fits together. That would move me forward on my USB understanding far more than anything else. Concrete examples. And with timing information!

hidtool works on Linux, does not work on Windows 7

Hello,
I made a device based on the hid-data demo. It works great on Linux (tested on two machines), but hidtool read fails on Windows 7 64-bit (also tested on two different machines other then the Linux ones):
error reading data: Communication error with device

When I unplug it hidtool returns device not found.
The device is correctly enumerated and shown in device manager without warnings.
Hardware itself is not faulty, as I successfully used bootloadHID to upload new firmware in Windows 7.

I also tried changing REPORT_COUNT (16) back to defaults, though I've built a different device using an identical descriptor that actually works under Windows.

I did a communication dump using Wireshark:

The device is probably connected after packet 53.
I try to execute hidtool read at packet 77 and then again at packet 83.

Need help identifying unreported net traffic.

Running 10.9.1 and latest LS.

I have the Network Monitor running, and it reports little, if any net traffic.

But I also use a program called XResource Graph, that monitors net traffic and reports a constant stream of 476-480K/s receiving.

In Activity Monitor mDNSResponder is receiving some packets: half a dozen every few seconds.
Overall, Activity Monitor reports receiving negligible amounts of incoming traffic: less than 100 bytes/sec.

Maybe it's a bug in XResource Graph. Are there any other known ways of finding traffic that LS and Activity Monitor might miss?

I figured out that the only change in hidtool.c I made is at line 94 - I decreased buffer size to print just 8 bytes (they wrap around at the device anyway). I reverted back to 129 bytes as in the stock demo and now it works on Windows. I still don't get why it worked modified on Unixes.

Same Here!

I'm on OS 10.8.5 and just upgraded to 3.3 and could not open either Preferences or Rules - the infamous beach ball of death appears whenever doing so

I tried reinstalling v3.3 a few times to no avail and then tried installing the nightly build v3.3.1 a few times to no avail.
I checked the system Activity Monitor and found that there are Two Instances of "Little Snitch Agent" running - each consuming 20-30% of system resources at any given time (without trying access Preferences or Rules.
I tried force quitting one of the Little Snitch Agents but a new second Little Snitch Agent auto loads each time.

At this point,
- LS network monitoring is working properly,
- I cannot launch Preferences or Rules without LS hanging up.
