5 | ================================== | ||
6 | The auerswald USB kernel driver connects your linux 2.4.x | ||
7 | system to the auerswald usb-enabled devices. | ||
8 | |||
9 | There are two types of auerswald usb devices: | ||
10 | a) small PBX systems (ISDN) | ||
11 | b) COMfort system telephones (ISDN) | ||
12 | |||
13 | The driver installation creates the devices | ||
14 | /dev/usb/auer0..15. These devices carry a vendor- | ||
15 | specific protocol. You may run all auerswald java | ||
16 | software on it. The java software needs a native | ||
17 | library "libAuerUsbJNINative.so" installed on | ||
18 | your system. This library is available from | ||
19 | auerswald and shipped as part of the java software. | ||
20 | |||
21 | You may create the devices with: | ||
22 | mknod -m 666 /dev/usb/auer0 c 180 112 | ||
23 | ... | ||
24 | mknod -m 666 /dev/usb/auer15 c 180 127 | ||
25 | |||
