10 This is a driver for the TI-GRAPH LINK USB (aka SilverLink) cable, a cable
11 designed by TI for connecting their TI8x/9x graphing handhelds to a computer
14 If you need more information, please visit the 'SilverLink drivers' homepage
19 A TI calculator/handheld of course and a program capable to communicate with
20 your calculator. A good choice is TiLP (http://www.tilp.info).
24 You must have first compiled USB support, support for your specific USB host
25 controller (UHCI or OHCI).
27 Next, (as root) from your appropriate modules directory (lib/modules/2.5.XX):
30 insmod usb/usb-uhci.o <OR> insmod usb/ohci-hcd.o
33 If it is not already there (it usually is), create the device:
35 mknod /dev/tiglusb0 c 115 16
37 You will have to set permissions on this device to allow you to read/write
40 chmod 666 /dev/tiglusb0
42 Now you are ready to run a linking program such as TiLP. Be sure to configure
47 You can set these with: insmod tiglusb NAME=VALUE
48 There is currently no way to set these on a per-cable basis.
53 DESC: Timeout value in tenth of seconds. If no data is available once this
54 time has expired then the driver will return with a timeout error.
58 The following problem seems to be specific to the link cable since it appears
59 on all platforms (Linux, Windows, Mac OS-X). A guy told me it was a common but
60 weird behaviour with Cypress microcontrollers (it uses an CY7C64013).
62 In some very particular cases, the driver returns with success (no error) but
63 without any data. The application should retry a read operation at least once.
65 This problem and the need to issue IOCTL_TIUSB_RESET_PIPES before doing any
66 packet transfer (like TI's software do) make this driver difficult to use in
71 You can email me at roms@tilp.info. Please prefix the subject line
72 with "TIGLUSB: " so that I am certain to notice your message.
73 You can also mail JB at jb@jblache.org: he has written the first release of
74 this driver but he better knows the Mac OS-X driver.
78 The code is based on dabusb.c, printer.c and scanner.c !
79 The driver has been developed without any support from Texas Instruments Inc.
