![]() HashMap usbDevices = usbManager.getDeviceList() įor (Map.Entry entry : usbDevices. ![]() UsbManager usbManager = (UsbManager) getSystemService(Context.USB_SERVICE) Here is my code, it simply tries to get a device list, and tries checking the deviceID and vendorID, but it never returns any information about my custom flash drive, so the loop below never runs because the list contains no elements, except when i use a regular flash drive it works. I tried using a normal flash drive that contains a real file system, and the Android API can see that perfectly fine, but for some reason it can NOT see the flash drive containing the raw data and no file system, even thought VirtualBox can see it when I click on the USB settings in VistualBox and try to set the USB filter, it already has the vendorID and DeviceID listed of the drive containing just the raw data and no file system. ![]() Prerequisite Android SDK platform-tools from or Android Studio. Connect an instance to a developer's tool (IDE), such as Android Studio, VS Code, JetBrains Rider, etc. I dont know if its because there is no file system on there, but I thought mass storage does NOT care if you have a file system or not, it just read and writes what you tell it? It can be used with a Genymotion Device image instance to: Control an instance Android OS. VirtualBox can see the vendorID and deviceID when the flash drive is plugged into Windows, but when I run the Android program in Android Studio, The Android API doesnt see the drive when I try to get a list of USB devices. In VirtualBox I set the USB filter to the device and product ID of the USB flash drive I was using (that same flash thumb drive that contains only data and no file system). So in order to do this (to debug the USB host on Android), I installed VirtualBox and GenyMotion android Emulator that supports Android USB Host. This "reader" program works in Windows, I have to write this same "reader" program for Android. I have also written a "reader" program for Windows that can read and make sense of this raw data, but only my program knows the format (which is again the goal). Windows doesnt even assign a drive number to it because it no longer contains any recognizable file system (which is the goal). The result is that the flash drive now contains only raw data. View karim.I have written a WINDOWS program using Visual C/C++ that uses the low level LIBUSB functions to write raw data to a flash thumb drive.mako on Android: How to Include Line Numbers, Class Names, and Method Names in Your Log Statements.Karim Varela on Android: How to Include Line Numbers, Class Names, and Method Names in Your Log Statements.Dismiss Keyboard (in Android) – Brooks Web Pro on Android: How to Hide Keyboard By Touching Screen Outside Keyboard.Select Plugins and click Browse repositories.
