USB hosts hubs transceivers Forum Discussions
For a student project I have to control the CY7C67300 on a Xilinx Virtex-4 ML403 board. I use the chip co-processor mode and communicatie with it with a FPGA. The protocol I use is HPI and the programlanguage is VHDL. I use the AN6010 as a guidline for programming everything. Everthing works fine until I send my first TD_List. Normally after you send the list and you read the SIE1msg register you should see 0x1000. But all I get is 0x0000. When i read the HPI Status port I see that the 5th bit isn't set. I have no idea how to fix the problem. I've tried everything (checking the timings, ect)

Show LessI am looking for a board that can act simultaneously as a USB device and as a TCP/IP client over ethernet. I am considering the CY3662. Does anyone know if this board has been used this way before? If so, are there code examples available?
I'm new to Cypress, so I'm not sure how to navigate around and find code/documentation for devices. It looks like resources for the CY3662 are limited. I've looked at the "Getting Started" guide, and its fairly brief.
Show LessThanks for the response. Show Less
I'm having problems with the CY7C65640A hub with a new Quad core machine.
The machine is a IP35 Pro from ASUS that uses the Intel ICH9 chipset USB controller.
I'm am using the CY7C65640A with no EEPROM. (The default setting used)
Of two downstream ports,
One port streams High speed compressed video. When streaming starts, no data
is received and the computer deadlocks.
On the other port, single high speed reads and writes appear OK and large bulk reads are intermittent.
Other symptoms include random driver load failures when USB plugged in.
I tried several PCI express hub expanders using two different NEC chips. Both worked flawlessly work both downstream ports.
Thanks Show Less
