 *  ===== HISTORY of changes in //depot/misc/projects/tps/usb/usbpriv.h
 *  
 *  30/Jun/04 #37 mrhines Endpoint change now on by default for SE* (and all other configurations)
 *  17/Jun/04 #36 lee Changed endpoints off by default for SE*, on for all others.
 *  15/Jun/04 #35 lee Found Card Reader problem, USB_PHY_EP_FIX=1 is the default again.
 *  15/Jun/04 #34 lee Made USB_PHY_EP_FIX=0 the default, i.e., no endpoint switch.
 *  15/Jun/04 #33 lee Increase max no. of endpoints to 9, common defs for EP
 *                    numbers, set -DUSB_PHY_EP_FIX=0 to revert to old ep numbers.
 *  3/Jun/04 #32 lee Change FIFO_DATA_ADDRESS to RAM addr rather than FIFO addr.
 *  28/May/04 #31 lee Added address of FIFO for USBH 2.0 work-around.
 *  12/May/04 #30 lee Make no scan/debug interface for CH* the default.
 *  10/May/04 #29 lee Support config w/o scanner and/or debug channels, e.g., CH*
 *  10/May/04 #28 lee Remove RAM_FLASH debug code.
 *  10/May/04 #27 lee Remove GRINDSTONE build option
 *  28/Apr/04 #26 lee Give USB tasks different priorities to help with debugging.
 *  7/Apr/04 #25 lee Back out HPC interface (function replaced by tps debug)
 *  2/Mar/04 #24 lee USB2.0 default packet size, HS_BULK_SIZE,
 *  now 512. May be overridden by defining HS_BULK_SIZE explicitly
 *  or defining DEFAULT_ARBITER (HS_BULK_SIZE then set to 64)
 *  12/Feb/04 #23 lee Force USB buffers to non-cachable memory using ALIGN macros.
 *  29/Jan/04 #22 lee If ARBITER_TEST defined, use 256 for USB 2.0 (high-speed) packet size.
 *  28/Jan/04 #21 lee Make USB2.0 default; still possible to override with "-DFULL_SPEED_ONLY=1"
 *  26/Jan/04 #20 lee Allow value of HS_BULK_SIZE to be overridden.
 *  23/Jan/04 #19 lee Make memory card reader the default unless explicitly disabled
 *  23/Jan/04 #18 lee Changed high-speed packet size from 512 to 64.
 *  8/Jan/04 #17 lee Added ENDPOINT_PRIMED macro
 *  13/Nov/03 #15 lee Don't allow HPC option for GRINDSTONE or boot code.
 *  10/Nov/03 #14 lee Changes for HPC for sending printf's to host PC
 *  31/Oct/03 #13 lee Fixes to pass USB2.0 and HID compliance.
 *  29/Oct/03 #12 lee Increase MAX_STR_DESC_COUNT for UNBRIDLED
 *  15/Oct/03 #11 lee Undefine MEMORY_CARD_READER if GRINDSTONE build.
 *  14/Oct/03 #10 lee Name changes for RAM_FLASH (formerly DUMMY_FLASH)
 *  14/Oct/03 #9 pshread Debug printing disabled my default.  Too much spitting out serial port otherwise
 *  24/Sep/03 #8 lee Added memory card function prototype, Gridstone changes.
 *  22/Sep/03 #7 lee Fix PRINTER_IFACE definition for GRINDSTONE
 *  19/Sep/03 #6 lee Work continues on Mass Storage Class for memory cards.
 *  18/Sep/03 #5 lee Fixes for memory card code.
 *  29/Aug/03 #4 lee Made memory card reader depend on MEMORY_CARD_READER manifest
 *  28/Aug/03 #3 lee Changes for Memory Card interface, added ASSERT for boot code.
 *  27/Aug/03 #2 emiller Removed "ASSERT" definition
 *  21/Aug/03 #1 lee Created
 *  
 *  End of Zoran Standard Header
