USB Basic Device Driver Support

changes in 10.224: USBD: 1) make USBD.SYS compatible with OS/4 kernel (to properly display HUB info in OS/2 Hardware Manager), USBD.SYS will still properly load on the standard OS/2 kernel 2) fixes so that USB will work from a booted up commandline 3) back out Transaction Translater (TT) reset introduced in 10.223. Looks like some hubs don't like this command if issued directly after hub ports power on (thanks Barry Landy) 4) change all delay timing in the root hub processing in the HC drivers ((U|O|E)HCD.SYS) from using blocking to using delay timers. This should reduce device attach problems on bootup. The complete solution would also involve doing the same for USBD.SYS but that has not been done due to lack of time.

changes in 10.222: USBD: 1) change HC reset and root hub enumeration logic: first, reset all EHCI HCs, then reset all UHCI/OHCI HCs, then start root hub enumeration for all EHCI root hubs, then start root hub enumeration for all UHCI/OHCI root hubs USBWAV: 1) remove sample rate conversion, instead, add conversion from 24-bit/32-bit to 16-bit so that you can replay 24-bit/23-bit files to a 16-bit audio device via MMPM (double click on sound file, ...) It also adds a subpage to the Multimedia Setup Object (under "USB Adapter Wave") to disable/enable that feature for example if you do have a USB audio device that is natively capable of playing 24-bit or even 32-bit. Can be used along with the conversion USBAUDIO provides (see below). USBWAV continues to support A-law and u-law codecs. PLEASE RERUN THE USBWAV INSTALLATION EHCI: 1) fix interrupt transfer driven devices (mouse,keyboard) by fixing bandwidth allocation and deallocation computation. That'll allow to properly use mice and keyboards on USB 2.0 hubs, in particular if isochronous devices (USB audio stick) are used on the very same hub (thanks Mikhail Zlobin for reporting this problem) USBAUDIO: 1) adding additional conversion for sample rates and/or bit resolutions (thanks Wim Brul) Wim has provided this complete list of what conversion is provided apart from the legacy sample rates (8 kHz, 11.025 kHz, 22.050 kHz) that continue to be supported. PLEASE RERUN THE USBAUDIO INSTALLATION. In general, if a bit resolution / sample rate is directly supported by the Hardware then no conversion will take place: +-----------------------------------------------------------+ | sampling rates 32-bit mono/stereo to 16/24/32-bit stereo | +------+------+------+------+-------+-------+-------+-------+-------+ | 44.1 | 48.0 | 88.2 | 96.0 | 176.4 | 192.0 | 352.8 | 384.0 | kHz | +------+------+------+------+-------+-------+-------+-------+-------+---+ | ok | down | down | down | down | down | down | down | 44.1 | H | +------+------+------+------+-------+-------+-------+-------+-------+ | | | ok | down | down | down | down | down | down | 48.0 | A | +------+------+------+------+-------+-------+-------+-------+-------+ | | | | ok | down | down | down | down | down | 88.2 | R | +------+------+------+------+-------+-------+-------+-------+-------+ | | | | | ok | down | down | down | down | 96.0 | D | +------+------+------+------+-------+-------+-------+-------+-------+ | | | | | | ok | down | down | down | 176.4 | W | +------+------+------+------+-------+-------+-------+-------+-------+ | | | | | | | ok | down | down | 192.0 | A | +------+------+------+------+-------+-------+-------+-------+-------+ | | | | | | | | ok | down | 352.8 | R | +------+------+------+------+-------+-------+-------+-------+-------+ | | | | | | | | | ok | 384.0 | E | +------+------+------+------+-------+-------+-------+-------+-------+---+ 1) 32-bit is converted to 16/24-bit by truncation. 2) mono is converted to stereo by sample duplication. 3) downsampling is done by throwing away samples. +-----------------------------------------------------------+ | sampling rates 24-bit mono/stereo to 16/24-bit stereo | +------+------+------+------+-------+-------+-------+-------+-------+ | 44.1 | 48.0 | 88.2 | 96.0 | 176.4 | 192.0 | 352.8 | 384.0 | kHz | +------+------+------+------+-------+-------+-------+-------+-------+---+ | ok | down | down | down | down | down | down | down | 44.1 | H | +------+------+------+------+-------+-------+-------+-------+-------+ | | | ok | down | down | down | down | down | down | 48.0 | A | +------+------+------+------+-------+-------+-------+-------+-------+ | | | | ok | down | down | down | down | down | 88.2 | R | +------+------+------+------+-------+-------+-------+-------+-------+ | | | | | ok | down | down | down | down | 96.0 | D | +------+------+------+------+-------+-------+-------+-------+-------+ | | | | | | ok | down | down | down | 176.4 | W | +------+------+------+------+-------+-------+-------+-------+-------+ | | | | | | | ok | down | down | 192.0 | A | +------+------+------+------+-------+-------+-------+-------+-------+ | | | | | | | | ok | down | 352.8 | R | +------+------+------+------+-------+-------+-------+-------+-------+ | | | | | | | | | ok | 384.0 | E | +------+------+------+------+-------+-------+-------+-------+-------+---+ 1) 24-bit is converted to 16-bit by truncation. 2) mono is converted to stereo by sample duplication. 3) downsampling is done by throwing away samples. +-----------------------------------------------------------+ | sampling rates 16-bit mono/stereo to 16/24-bit stereo | +------+------+------+------+-------+-------+-------+-------+-------+ | 44.1 | 48.0 | 88.2 | 96.0 | 176.4 | 192.0 | 352.8 | 384.0 | kHz | +------+------+------+------+-------+-------+-------+-------+-------+---+ | ok | down | down | down | down | down | down | down | 44.1 | H | +------+------+------+------+-------+-------+-------+-------+-------+ | | up | ok | down | down | down | down | down | down | 48.0 | A | +------+------+------+------+-------+-------+-------+-------+-------+ | | | | ok | down | down | down | down | down | 88.2 | R | +------+------+------+------+-------+-------+-------+-------+-------+ | | | | | ok | down | down | down | down | 96.0 | D | +------+------+------+------+-------+-------+-------+-------+-------+ | | | | | | ok | down | down | down | 176.4 | W | +------+------+------+------+-------+-------+-------+-------+-------+ | | | | | | | ok | down | down | 192.0 | A | +------+------+------+------+-------+-------+-------+-------+-------+ | | | | | | | | ok | down | 352.8 | R | +------+------+------+------+-------+-------+-------+-------+-------+ | | | | | | | | | ok | 384.0 | E | +------+------+------+------+-------+-------+-------+-------+-------+---+ 1) 16-bit is converted to 24-bit by zero extension. 2) mono is converted to stereo by sample duplication. 3) downsampling is done by throwing away samples. 4) upsampling is done by duplicating samples.

This is a maintenance release and includes minor fixes and enhancements. Specifically, this version fixes keyboard auto-repeat so that it works for all USB keyboards. This version also fixes the ability to use certain unusual types of USB 1.x devices when plugged into a USB 2.0 hub.
