  1. =============================
  2. Infinity Usb Unlimited Readme
  3. =============================
  4. Hi all,
  5. This module provide a serial interface to use your
  6. IUU unit in phoenix mode. Loading this module will
  7. bring a ttyUSB[0-x] interface. This driver must be
  8. used by your favorite application to pilot the IUU
  9. This driver is still in beta stage, so bugs can
  10. occur and your system may freeze. As far I now,
  11. I never had any problem with it, but I'm not a real
  12. guru, so don't blame me if your system is unstable
  13. You can plug more than one IUU. Every unit will
  14. have his own device file(/dev/ttyUSB0,/dev/ttyUSB1,...)
  15. How to tune the reader speed?
  16. =============================
  17. A few parameters can be used at load time
  18. To use parameters, just unload the module if it is
  19. already loaded and use modprobe iuu_phoenix param=value.
  20. In case of prebuilt module, use the command
  21. insmod iuu_phoenix param=value.
  22. Example::
  23. modprobe iuu_phoenix clockmode=3
  24. The parameters are:
  25. clockmode:
  26. 1=3Mhz579,2=3Mhz680,3=6Mhz (int)
  27. boost:
  28. overclock boost percent 100 to 500 (int)
  29. cdmode:
  30. Card detect mode
  31. 0=none, 1=CD, 2=!CD, 3=DSR, 4=!DSR, 5=CTS, 6=!CTS, 7=RING, 8=!RING (int)
  32. xmas:
  33. xmas color enabled or not (bool)
  34. debug:
  35. Debug enabled or not (bool)
  36. - clockmode will provide 3 different base settings commonly adopted by
  37. different software:
  38. 1. 3Mhz579
  39. 2. 3Mhz680
  40. 3. 6Mhz
  41. - boost provide a way to overclock the reader ( my favorite :-) )
  42. For example to have best performance than a simple clockmode=3, try this::
  43. modprobe boost=195
  44. This will put the reader in a base of 3Mhz579 but boosted a 195 % !
  45. the real clock will be now : 6979050 Hz ( 6Mhz979 ) and will increase
  46. the speed to a score 10 to 20% better than the simple clockmode=3 !!!
  47. - cdmode permit to setup the signal used to inform the userland ( ioctl answer )
  48. if the card is present or not. Eight signals are possible.
  49. - xmas is completely useless except for your eyes. This is one of my friend who was
  50. so sad to have a nice device like the iuu without seeing all color range available.
  51. So I have added this option to permit him to see a lot of color ( each activity change the color
  52. and the frequency randomly )
  53. - debug will produce a lot of debugging messages...
  54. Last notes
  55. ==========
  56. Don't worry about the serial settings, the serial emulation
  57. is an abstraction, so use any speed or parity setting will
  58. work. ( This will not change anything ).Later I will perhaps
  59. use this settings to deduce de boost but is that feature
  60. really necessary ?
  61. The autodetect feature used is the serial CD. If that doesn't
  62. work for your software, disable detection mechanism in it.
  63. Have fun !
