5 | Version 0.8.7.2: | |
6 | Call snd_card_free() instead of snd_card_free_in_thread() to prevent oops with dead keyboard symptom. | |
7 | Tested ok with kernel 2.6.12-rc2. | |
8 | ||
1da177e4 LT |
9 | 2004-12-14 Karsten Wiese |
10 | Version 0.8.7.1: | |
11 | snd_pcm_open for rawusb pcm-devices now returns -EBUSY if called without rawusb's hwdep device being open. | |
12 | ||
13 | 2004-12-02 Karsten Wiese | |
14 | Version 0.8.7: | |
15 | Use macro usb_maxpacket() for portability. | |
16 | ||
17 | 2004-10-26 Karsten Wiese | |
18 | Version 0.8.6: | |
19 | wake_up() process waiting in usX2Y_urbs_start() on error. | |
20 | ||
21 | 2004-10-21 Karsten Wiese | |
22 | Version 0.8.5: | |
23 | nrpacks is runtime or compiletime configurable now with tested values from 1 to 4. | |
24 | ||
25 | 2004-10-03 Karsten Wiese | |
26 | Version 0.8.2: | |
27 | Avoid any possible racing while in prepare callback. | |
28 | ||
29 | 2004-09-30 Karsten Wiese | |
30 | Version 0.8.0: | |
31 | Simplified things and made ohci work again. | |
32 | ||
33 | 2004-09-20 Karsten Wiese | |
34 | Version 0.7.3: | |
35 | Use usb_kill_urb() instead of deprecated (kernel 2.6.9) usb_unlink_urb(). | |
36 | ||
37 | 2004-07-13 Karsten Wiese | |
38 | Version 0.7.1: | |
39 | Don't sleep in START/STOP callbacks anymore. | |
40 | us428 channels C/D not handled just for this version, sorry. | |
41 | ||
42 | 2004-06-21 Karsten Wiese | |
43 | Version 0.6.4: | |
44 | Temporarely suspend midi input | |
45 | to sanely call usb_set_interface() when setting format. | |
46 | ||
47 | 2004-06-12 Karsten Wiese | |
48 | Version 0.6.3: | |
49 | Made it thus the following rule is enforced: | |
50 | "All pcm substreams of one usX2Y have to operate at the same rate & format." | |
51 | ||
52 | 2004-04-06 Karsten Wiese | |
53 | Version 0.6.0: | |
54 | Runs on 2.6.5 kernel without any "--with-debug=" things. | |
55 | us224 reported running. | |
56 | ||
57 | 2004-01-14 Karsten Wiese | |
58 | Version 0.5.1: | |
59 | Runs with 2.6.1 kernel. | |
60 | ||
61 | 2003-12-30 Karsten Wiese | |
62 | Version 0.4.1: | |
63 | Fix 24Bit 4Channel capturing for the us428. | |
64 | ||
65 | 2003-11-27 Karsten Wiese, Martin Langer | |
66 | Version 0.4: | |
67 | us122 support. | |
68 | us224 could be tested by uncommenting the sections containing USB_ID_US224 | |
69 | ||
70 | 2003-11-03 Karsten Wiese | |
71 | Version 0.3: | |
72 | 24Bit support. | |
73 | "arecord -D hw:1 -c 2 -r 48000 -M -f S24_3LE|aplay -D hw:1 -c 2 -r 48000 -M -f S24_3LE" works. | |
74 | ||
75 | 2003-08-22 Karsten Wiese | |
76 | Version 0.0.8: | |
77 | Removed EZUSB Firmware. First Stage Firmwaredownload is now done by tascam-firmware downloader. | |
78 | See: | |
79 | http://usb-midi-fw.sourceforge.net/tascam-firmware.tar.gz | |
80 | ||
81 | 2003-06-18 Karsten Wiese | |
82 | Version 0.0.5: | |
83 | changed to compile with kernel 2.4.21 and alsa 0.9.4 | |
84 | ||
85 | 2002-10-16 Karsten Wiese | |
86 | Version 0.0.4: | |
87 | compiles again with alsa-current. | |
88 | USB_ISO_ASAP not used anymore (most of the time), instead | |
89 | urb->start_frame is calculated here now, some calls inside usb-driver don't need to happen anymore. | |
90 | ||
91 | To get the best out of this: | |
92 | Disable APM-support in the kernel as APM-BIOS calls (once each second) hard disable interrupt for many precious milliseconds. | |
93 | This helped me much on my slowish PII 400 & PIII 500. | |
94 | ACPI yet untested but might cause the same bad behaviour. | |
95 | Use a kernel with lowlatency and preemptiv patches applied. | |
96 | To autoload snd-usb-midi append a line | |
97 | post-install snd-usb-us428 modprobe snd-usb-midi | |
98 | to /etc/modules.conf. | |
99 | ||
100 | known problems: | |
101 | sliders, knobs, lights not yet handled except MASTER Volume slider. | |
102 | "pcm -c 2" doesn't work. "pcm -c 2 -m direct_interleaved" does. | |
103 | KDE3: "Enable full duplex operation" deadlocks. | |
104 | ||
105 | ||
106 | 2002-08-31 Karsten Wiese | |
107 | Version 0.0.3: audio also simplex; | |
108 | simplifying: iso urbs only 1 packet, melted structs. | |
109 | ASYNC_UNLINK not used anymore: no more crashes so far..... | |
110 | for alsa 0.9 rc3. | |
111 | ||
112 | 2002-08-09 Karsten Wiese | |
113 | Version 0.0.2: midi works with snd-usb-midi, audio (only fullduplex now) with i.e. bristol. | |
114 | The firmware has been sniffed from win2k us-428 driver 3.09. | |
