This did not resolve the problem, and we wrongly concluded that this meant it wasn't a problem of wrong info being retained. In USBDeview we deleted all records associated with VID_16c0.

In previous attempts to fix this problem, we used USBDeview to view information that Windows was retaining for various USB devices.

This mistaken association could perhaps happen during development with the Teensy, or perhaps due to interrupting the process of finding the right driver during initial plug-in. It seems that if that process decides on the "wrong" driver for some reason (for example, chooses the mouse driver mouhid.sys), then the system will be stuck with that choice in future.
#WINDOWS 10 TEENSY DRIVER SERIAL#
There are separate keys for the different sub device Product Ids corresponding to Mouse, Keyboard, Debug and Joystick, and possibly Serial (depending on the setting for USB type in the Arduino environment), and this info may be stored separately per USB socket. It appears that the function of some of these keys is to remember the result of the first time the device was plugged in, and a driver found. The registry stores a lot of keys in various places that contain the Vendor Id used by the joystick: VID_16c0. On machines that read the joystick properly, Windows associates the joystick with hidusb.sys. The USB activity during hot-plug indicates that on the problem machine, Windows associates driver mouhid.sys with the joystick.
On other machines the Teensy USB joystick works fine.ĭelete from the registry all keys containing VID_16c0.Īfter a lot of inspection of Teensy USB traffic with USBLyzer, I think we have an answer and a fix for the problem. This concerns Teensyduino USB joystick, on a particular "problem machine", showing up in joy.cpl, but with the Properties window displaying blank, as though the joystick contains no analog or digital variables. What we don't know is whether S+K+M+L would have worked with Arduino etc not installed (and/or whether that would prompt Windows to look for a serial driver - doh!). The non-working condition was encountered prior to installing Arduino etc. These results (K+M+J bad, S+K+M+J good) were obtained after installing Arduino 1.0.4, Teensyduino 1.13 and teensy serial driver onto The Problem Machine. So, we have the workaround of using SUB Type = S+K+M+J, but it's worrisome that just K+M+J didn't work.

We also tried deleting all the serial code from example Complete (and also the examples that don't use serial), and these moves didn't result in proper behavior on The Problem Machine. So is seems that there is something in the config_descriptor or joystick_hid_report_desc, when it's compiled with "K+M+J", that causes The Problem Machine to think there are no data items for the Joystick.īear in mind, again, that "K+M+J" works fine when Teensy is plugged into the six different other machines that we tried. If instead we switch USB Type to "Serial + Keyboard + Mouse + Joystick", then the joystick works fine on The Problem Machine. This is the behavior when the Teensy code is compiled with the Arduino "USB Type" set to "Keyboard + Mouse + Joystick".
I.e., Windows sees the joystick device, can read its device info, but mysteriously the number of data items actually available is zero. Notably, the panel which shows data from the HID Report shows Max axes 6, Number of axes 0, Max buttons 32, Number of buttons 32.
Joystick Tester on the Problem Machine is similarly without data. However, when plugged into a particular laptop ("The Problem Machine", Lenovo Z575 Win 7 Home), although the Teensy appears in joy.cpl, the Properties window is blank (no graph of X-Y, slides or switches).Īnother user also reported this kind of problem: When plugged into several different Windows desktops or laptops (mostly Win 7 pro), this works fine, for example as seen in joy.cpl, or using Joystick Tester ( ). We have the guts of an analog joystick (with switches) wired to the Teensy, running the example code.
