QUESTION

cannot claim usb interface more than 64 times

Asked 2021-Dec-09 at 10:10

I have an app that needs to maintain a long (indefinite) connection to a usb device and print a potentially unlimited number of times to it. So, it needs to make a lot of claims on the same device interface.

Eventually my app breaks because on the 65th claim I get a LIBUSB_ERROR_ACCESS error thrown. Is it possible to fix this with node-usb? Possibly related to

environment and hardware

ENQ in this sample doesn't mean the three letters E, N and Q. It refers to the Unicode control character ENQUIRY U+0005, which also happens to be 0x05 in ASCII.

To represent that in a string, use \u0005: .transfer("\u0005M");

For the sake of readability you could put that into a constant:

Electron 11 has a newer version of V8 JS engine which the native module usb@1.6.3 with a version of the std library not set to std=c++14 thus that doesn't support what V8 now requires.

This is known issue and you can read about it at these PRs #376, #394, #400 and the fix has been merged today (January 30 2021) with this PR #407 and there is a new release on NPM usb@1.6.4.

Now your steps are working for me on Ubuntu 20.04 and ElectronRebuild.js runs with no errors after installing latest usb module:

I have found multiple questions similar to this but none of the solutions seems to be working for me. I am trying to use usb library (https://www.npmjs.com/package/usb) to access usb devices, and it worked perfectly as long as it was a command-line test application without Electron. I installed Electron on the Ubuntu 14 computer I'm working with npm install electron --save-dev and the test app provided by their website works too, but when I add my usbtools.js module
