Dear Sir :
Used PSoC Creator 4.4 & EZ-PD CCGX DOCK SDK , change device item -> generate application have some errors.
Please help us to fix it , thanks.Show Less
When using CYUSB4357, whether its SPI ROM BIN FILE can use the BIN FILE of CYUSB4347 (Firmware: CYUSB4347-BZXC_FW_2_0_0.bin), the function of Signed Firmware Update is not required at this time.
we're having big problems getting the parts CY7C65642-48AXC. We have already contacted the Infineon support, but they referred me to this forum. We have placed orders at Mouser, Digikey, Farnell, ... partly over one year ago, without success.
Do you know when the parts will be available again?
In customer side, they use CYUSB3314-88LTXC to design in USB3.0 HUB with two ports DS0 and DS1， they find the PC's explorer can't appear the DS1 device when continuous plug and unplug USB3.0 U disk, the probability is about 2%. when the issue appear, they use DS0 ports, the DS0 is good. they have to software reset the HUB, the issue is disappear. Now, they want to read the hub registers issue status frist( include rest flag bit) to know the HUB got to which staus, I can't find any register description, How can I catch it whether do you like to share( whether I need build a mycase)

This question is related to the HX3 design discussed in this review.
The HX3 hub was manufactures as in the above mentioned design and it looks like it works ok, we use it to connect a USB camera module (AR0144) to the PC/Laptop. The camera module is USB 3 and has a micro-B USB connector, we use a micro-B USB to type-C cable to connect the camera module to the HX3 hub.
we have 2 types of micro-B to type C cable (see attached cable A and cable B), everything works good with cable A but when connecting the camera module to the HX3 hub using cable B we get a "USB device not recognized". we connected the camera module directly to the PC with cable B and it works good, we also tested the camera module with cable B connected to a commercial USB-3 hub and it also works good.
any ideas what can male cable B not work with the HX3?
We use the CY7C65640A-LTXC on multiple boards and I appreciate that it has been obsolete for some time now.
We have managed to source this part through various sources & avoid the need to update our PCBs until now.
There is no direct replacement listed but the CY7C65630-56LTXC appears to have the same pinout & functionality.
Can the CY7C65630-56LTXC be used as a direct pin for pin replacement?Show Less
There is a fault with the USB drive detection in the following situation.
The design contains iMx6 which has an internal USB hub that communicates with the external USB hub (Cypress CY7C65631-56LTXCT). The latter external hub switches itself off without reporting any faults to the processor when the USB drive is plugged after the system booted. This fault is reproducible and only occurs when no device has been plugged into the port during system power on. This has been occurring on current and previous boards involving the same Cypress hub.
This fault has not occurred when the Cypress CY7C65631-56LTXCT was bypassed and USB lines were connected straight into the processor.
Is there anything specific that the processor needs to tell the hub that could prevent the hub from powering off? All logs report no errors so is there any way we could configure the hub to echo something back before the fault occurs?
Customer Tesseract interested to know below information regarding USB hub controller CY7C65642-28LTXC.
1) Environmental condition ( Pb free / Halogen free)
2) MTBF report
3) ESD ( HBM/CDM/MM)
Thanks & regards,
Event: After turning on the power to the HUB, there are cases where it is recognized as 650B or 650C instead of the Product ID 650A / 6508 originally recognized by the device manager of the Windows 10 PC connected via USB. At this time, the expected driver is not assigned correctly, and communication failure under the HUB occurs.The USB driver is a generic usbhub3.inf.
