Closed taoyuan closed 2 years ago

taoyuan commented 9 years ago

I have installed and tested the awesome project. It work fine with keyboard and mouse, although a little slow.

However, it is not so lucky with thermal printers. Here is the output:

And after a few seconds, it exit without any further message. Before the usb-mitm process exit, the host can recognize the device, but can not operate it.

Thanks for any help.

dmesg has messages:

dominicgs commented 9 years ago

This is a known issue (it comes up about once per month). There is a workaround included with recent git commits. Are you running the latest code?

taoyuan commented 9 years ago

@dominicgs Thanks for your reply. I think I'm running the latest code. I cloned the code directly form USBProxy github master branch yesterday.

dominicgs commented 9 years ago

You should be hitting this code long before you run out of memory: https://github.com/dominicgs/USBProxy/blob/45191b7269b1c9dea10aa5fa9cbdad73b34dddd2/src/lib/SafeQueue.hpp#L31

Can you run usb-mitm with the -d or -dd option?

taoyuan commented 9 years ago

OK. Here is the full output for -d option:

dominicgs commented 9 years ago

This is strange. Are you running on a BeagleBone Black? Are you using the OS image that I published on the releases page?

taoyuan commented 9 years ago

Yes. I'm running on a BeagleBone Black. I have tested on the OS image that published on the releases page before, and had the problem. So I compiled a new OS version based on the 4.1 kernel according to the related documents, of cause opened GadgetFS function.

The outputs above is running on the 4.1 kernel OS image.

taoyuan commented 9 years ago

I ran once again on your OS image with the latest version. And the outputs is:

This is very strange. We've already included code to work around this problem.

Could you list the version of everything? libUSB, the git revision of the code? Did you install the code or are you running it from the build directory?

taoyuan commented 9 years ago

According to the readme, I compiled USBProxy:

mkdir src/build
cd src/build
cmake ..
make
sudo make install
sudo ldconfig

And run with sudo usb-mitm -l -d

Here is the code version info:

Which I found very strange O.O

devilicecream commented 8 years ago

@dominicgs any thoughts on this one?

dominicgs commented 8 years ago

I'm not sure I see the problem in the output from usb-mitm. Is it not passing through traffic to the printer?

You may want to blacklist the usblp module so that the host doesn't try to claim it, but that doesn't appear to be causing a problem.

devilicecream commented 8 years ago

The traffic is indeed not being relayed, the problem I see in the log is this line:

Warning: queue fills up! Feel free to search the bug in either the driver or usbproxy.

Looks like the queue doesn't get freed because it can't write on the output port. Any idea of why this happens?

dominicgs commented 8 years ago

USBProxy appears to be polling one of the EPs on the printer, but the host isn't polling USBProxy at the same rate. Dropping these packets when the queue is full stops us from running out of memory and appeared to work for other users who have tried this with printers.

Maybe we need to use a smarter approach, we could stop polling the EP once there are X packets in the queue. However, I'm not sure that is going to solve your problem because you're not getting any traffic passed on the other EPs.

taoyuan commented 8 years ago

It sounds like reasonable about the memory issue.

But the main problem is block. I tried to send a print instruction before queue is full and exiting, usb-mitman has no response. It seems like that gadgetfs has not transfer all requests from host to device including data of endpoints.

dominicgs commented 8 years ago

Yes, that's strange. I would expect data going to the printer to be sent without problem. Have you tried using usbmon on the BBB to see what is being sent to the printer?

taoyuan commented 8 years ago

I haven't tried using usbmon.

But I tried using node.js to implement similar functionality, and found that the printer can not process control request [00 09 01 00 00 00 00 00], it throws some transfer error.

devilicecream commented 8 years ago

Another two cents on this one. I'm trying to figure out what throws the Error sending setup packet: Pipe error at the start, and I found this code in DeviceQualifier.cpp

DeviceQualifier::DeviceQualifier(Device* _device,DeviceProxy* proxy) {
        device=_device;
        usb_ctrlrequest setup_packet;
        setup_packet.bRequestType=USB_DIR_IN | USB_TYPE_STANDARD | USB_RECIP_DEVICE;
        setup_packet.bRequest=USB_REQ_GET_DESCRIPTOR;
        setup_packet.wValue=USB_DT_DEVICE_QUALIFIER<<8;
        setup_packet.wIndex=0;
        setup_packet.wLength=10;
        int len=0;
        if (proxy->control_request(&setup_packet,&len,(__u8 *)&descriptor)) {
               descriptor.bLength=0;
               configurations=NULL;
               return;
        }

The value (decimal) sent to the device are:

bRequestType: 128 bRequest: 6 wValue: 1536 wIndex: 0 wLength: 10 timeout: 500

And I found this http://www.keil.com/support/man/docs/rlarm/rlarm_usb_descript_dev_qualifier.htm, saying that if a full-speed only device receives a GetDescriptor() request for a device_qualifier, it must respond with a request error. Then, the host must not make a request for an other_speed_configuration descriptor. Therefore, is it the Pipe error ok in the case of a full-speed only device? Should it be handled better?

dominicgs commented 8 years ago

That seems like a reasonable suggestion, I think the error should definitely be handled cleanly.

I can't exactly remember the situation, but I seem to remember that there is something strange about the way that gadgetfs or musb-hdrc handles full/high speed devices. I believe it always requires a second set of descriptors to present itself as a high speed device, but I can't remember why.

palesius commented 8 years ago

This is equally vague. But I think gadgetfs doesn't let us directly respond to the initial descriptor request. We need to provide both and it handles it all behind the scenes, depending on what is requested. On Nov 12, 2015 1:38 PM, "Dominic Spill" notifications@github.com wrote:
