RAM Allocation in the FX2 vs. FX
The FX (and EZ-USB) isochronous buffers were located at 0x2000-0x2800. The FX2 does not seem to have implemented RAM in this area. For a stand-alone application, the total amount of RAM (internal) is insufficient. Disabling the ISO endpoints made an extra 2K RAM available. Does the FX2 have any options as this?

Maximum Packet Sizes for FX2/FX2LP in Full-speed Mode.
The FX2/FX2LP Technical Reference manual says the buffers appear smaller when the FX2/FX2LP runs at full speed and that packets are fixed at 64 bytes for non-Iso types. Does this mean that we cannot take advantage of the larger (slave) FIFO sizes - such as 512 bytes for bulk transfers - when using a PC that does not support high speed ?

Problem in firmware running from the EEPROM in FX2
I am using an EZ-USB FX2 with an AT24C64 EEPROM attached. When code is downloaded hrough the soft download feature, the device enumerates correctly and behaves perfectly. When the code is downloaded to the EEPROM, the device enumerates correctly as "USB Device" but the firmware does not run properly.
The first eight bytes in the EEPROM are:
"B2 47 05 31 21 00 00 00"
What could be wrong?

Difference in FX2/FX2LP reported pipe order between USB 2.0 and USB 1.1 hosts
In dscr.a51, my pipes are defined as:
pipe0: endpoint 2 OUT
pipe1: endpoint 1 OUT
pipe2: endpoint 2 IN
pipe3: endpoint 1 IN
On a computer with USB 2.0, everything is okay (i.e. all pipes are reported correctly and in the right order), but on a computer with USB 1.1, the pipe order changed to:
pipe0: endpoint 1 OUT
pipe1: endpoint 1 IN
pipe2: endpoint 2 OUT
No matter how I change the dscr.a51 (different order, less endpoints), there are always 3 pipes and endpoints reported on a USB 1.1 host. What could be the problem?

EZ-USB.SYS Does not Support Overlapped I/O
I am trying to do overlapped I/O for the DeviceIoControl call. It is performing CreateFile calls with the file overlapped flag. The problem is that the code in DeviceIoControl never exits, even though it is called with the overlapped I/O flag. Could it be that there is no support for that in the ezusb.sys driver?
