augustss df20cb2972 Change the operation of the USB event thread. Before it only performed 
USB device discovery, now it can also perform (short) tasks for device
drivers that need a process context, but don't have one.
This is not pretty, but better than using busy-wait in an interrupt context.

augustss 79f0bd6e1f Update many URLs. 2000-12-29 01:24:55 +00:00
augustss d71044b313 Don't give up so easily if the device does not respond properly. 
Mostly from Nick Hibma (FreeBSD).
 2000-09-24 02:08:38 +00:00
augustss 4b45dfbb69 Fix a device diconnect bug found by Christian Groessler <cpg@aladdin.de>. 2000-09-22 02:34:58 +00:00
augustss ed9486e158 Bring the coding style into the 80s, i.e., get rid of __P and use 
ANSI prototypes and declarations.

augustss 30c20f930f Change my email address. 2000-04-27 15:26:44 +00:00
augustss 46fb8de93a Use a 255 ms interrupt interval even if the descriptor in the hub asks 
for something else, because the spec says that it should be 255.
 2000-04-21 19:51:43 +00:00
augustss 3d9d091685 Change the exact sequence of commands when a hub is attached to follow 
Windoze more closely.  This makes more devices work.

After two years of doing USB work I've finally access to a USB protocol
analyzer.  Which means I should be able to mimic what Windoze does in
certain cases instead of just following the specs.  Following the specs
is not enough since the devices often don't.
 2000-04-21 16:05:50 +00:00
augustss fc72e72d7d Change (almost) all static to Static. The symbol `Static' can then be defined 
to `' or `static' depending on if you want to debug or not.
 2000-03-27 12:33:53 +00:00
augustss 7d05674ba7 Distinguish between device and interface classes. 
(I finally found a document that said that they were different.)
 2000-02-29 21:37:00 +00:00
augustss 0b2e81991d Avoid panic when a non-working hub is detached. 2000-02-12 23:44:16 +00:00
augustss 4b93911b25 Generate usb events on attach and detach. 2000-02-02 13:18:45 +00:00
augustss 481e8339dc Change the USB event mechanism to include more information about devices 
and drivers.  Partly from FreeBSD.
 2000-02-02 07:33:59 +00:00
augustss c3716a6bb9 Add an argument to usbd_open_pipe_intr() to specify the polling interval 
for an interrupt pipe in case we don't what what the descriptor suggests.
 2000-01-19 00:23:58 +00:00
augustss bb2a9b3008 Add some more debug printing. 1999-11-24 23:13:19 +00:00
augustss 3386c68b46 Cosmetic changes and some small improvements. From FreeBSD and Nick Hibma. 1999-11-18 23:32:25 +00:00
augustss 0d2fabdf26 A number of stylistic changes to increase readability (many suggested 
by Nick Hibma):
	use NULL not 0
	declare all local definitions static
	rename s/usbd_request/usbd_xfer/ s/reqh/xfer/
	rename s/r/err/
	use implicit test for no err
	KNF

augustss ff6a476e6c Rearrange the code a little so we can decide if we are in process 
or interrupt context in a reliable way.  Mainly used for DIAGNOSTIC.
 1999-09-13 19:18:17 +00:00
augustss b1a719a6cc Add a flag in the request to determine if the data copying is done by the 
driver or the usbdi layer.
 1999-09-12 08:23:42 +00:00
augustss 24251055bc Change the way the `struct device' base part of all driver softc are 
declared and accessed to make it more portable.  Idea from Nick Hibma, FreeBSD.
No functional changes.
 1999-09-05 19:32:18 +00:00
augustss 60179e2a13 Avoid null reference, from Nick Hibma, FreeBSD. 1999-09-02 18:13:50 +00:00
augustss 036a9c6974 Change some 'struct device' to 'bdevice'. From FreeBSD. 1999-08-28 21:42:35 +00:00
augustss 1f2661798f Make sure to mark the device as dying already in the (de)activate routine. 
This avoids access to it before the detach routine has blown it away.
 1999-08-23 22:55:14 +00:00
augustss f747201099 Move more of the transfer completion processing to HC independent code.

thread and the config detach method.

the spec) start up more reliably.
 1998-12-28 02:23:25 +00:00
