kandi X-RAY | hid Summary

hid is a C library typically used in Mobile, iOS applications. hid has no bugs, it has no vulnerabilities and it has low support. However hid has a Non-SPDX License. You can download it from GitHub.

The hid package is a cross platform library for accessing and communicating with USB Human Interface Devices (HID). It is an alternative package to gousb for use cases where devices support this ligher mode of operation (e.g. input devices, hardware crypto wallets). The package wraps hidapi for accessing OS specific USB HID APIs directly instead of using low level USB constructs, which might have permission issues on some platforms. On Linux the package also wraps libusb. Both of these dependencies are vendored directly into the repository and wrapped using CGO, making the hid package self-contained and go-gettable. Supported platforms at the moment are Linux, macOS and Windows (exclude constraints are also specified for Android and iOS to allow smoother vendoring into cross platform projects).

            USB device is enumerated correctly, but I never see a Setup transaction with bRequest equal to SET_ADDRESS
            Asked 2022-Mar-12 at 02:57

            Summary:
            While capturing USB traffic with wireshark, I see that devices enumerate properly when plugged in, but I never see the USB address getting assigned by the host.

            Details:
            I have tried this on both Windows 10 and Linux, and on several types of USB devices.
            I plug in a device, and capture the USB traffic using Wireshark. I expect to see a Setup transaction, with the data packet containing bRequest = 0x05 (SET_ADDRESS) and the wValue word containing the address to be assigned. But I never see this. The wireshark capture does show the other traffic I expect, like "GET DESCRIPTOR" request and response for the device, but no SET_ADDRESS. The simplest device I have is a USB 1.1 mouse, and the wireshark capture (summary lines only) is below.

            ...

            After more searching and experimenting, I have an answer.

            The Short Answer: Wireshark cannot show the USB address assignment transaction because it is not captured by the lower-level libraries used by wireshark.

            The Full Story: For some reason, it seems that the USB libraries used by wireshark do not capture the address assignment. The Windows version of these libraries, usbpcap, acknowledges this and other limitations on the web page. I did not find a similar disclaimer for the Linux version, but I suspect that the same technical limitations would affect both versions, and that's why I did not see the address assignment in wireshark on either Windows or Linux.

            To verify that the USB device enumeration was working even though not captured by wireshark, I programed a USB device on a TI ARM development board which had pins on the D+ and D- USB signal lines. I attached a logic analyzer and captured the enumeration sequence. The result was exactly as described in every USB tutorial. Here is the part of the enumeration sequence where the device address is assigned: After the token packet (with Setup Packet ID, still using address 0, endpoint 0), the Setup packet with a DATA0 PID contains in its payload the expected bRequest byte 0x05 (SET_ADDRESS) followed by the low byte of wValue, equal in this example to 0x26, the assigned address. Don't forget when looking at captures like this that the least significant bytes and bits come first. So to make sense of each byte, you need to flip the bit stream byte-by-byte before converting to the hex values. So 01100100b becomes 0010 0110 or 0x26.

            Automating conditional logic for database data checks in R
            Asked 2022-Mar-08 at 02:31

            I am trying to do a large data check for a database. Some fields in the database are hidden, so when I am doing the datacheck, I need to ignore all hidden fields. Fields are hidden based on conditional logic stored in the database. I have exported this conditional logic and have stored it in a dataframe in R. Now I need to automate the data check by somehow using the text string of a conditional argument to automate the script writing itself, which I do not think is possible, or finding a way around this problem.

            You can store the expression you want to evaluate as a string if you pass it into parse() first as explained in this answer.

            Here's a simple example of how you can store the expression in a column and then feed it to dplyr::case_when().

            Glad we tracked down your HID issue to a permissions problem in the comments.

            To run code as root in production/deployment, you'll need to set up a separate tool as a Launch Daemon, and configure it to start up on demand when your main app sends it an IPC (typically XPC) message.

            You have 2 main options for getting the launch daemon set up in the first place:

            • Embedding the daemon binary in your .app, and calling SMJobBless from your app's code to install it in the system. This will request entering the admin password from the user.
            • An installer .pkg that places your daemon binary somewhere fixed (e.g. below /Library/Application Support/YourAppName/) and places the corresponding launchd plist in /Library/LaunchDaemons.

            Note that you need to be quite careful to avoid opening gaping security holes when setting up a launch daemon. This series of articles is a good in-depth guide of what to do and what to avoid.

            Note also that SMJobBless is not permitted on the App Store, so this type of functionality simply isn't possible for apps distributed there.

            Pulling in JSEnquiry in your head tag will work just fine, but you need to allow time for it to download and parse. Calling it in the mounted hook doesn’t allow for that.

            I just had the same problem and solved it thanks to this question. The problem seems to be fibers.

            The steps I took to fix it:

            1. uninstall fibers: npm uninstall fibers
            2. delete package-lock.json & node_modules/
            3. install packages again: npm install

            Simply removing fibers from package.json isn't enough as Netlify seems to still find the package in package-lock.json.
