30.13.2 Host initialization
To initialize the core as host, the application must perform the following steps:
1. Program the HPRTINT in GINTMSK to unmask
2. Program the OTG_HS_HCFG register to select full-speed host
3. Program the PPWR bit in OTG_HS_HPRT to 1. This drives V BUS on the USB.
4. Wait for the PCDET interrupt in OTG_HS_HPRT0. This indicates that a device is
connecting to the port.
5. Program the PRST bit in OTG_HS_HPRT to 1. This starts the reset process.
6. Wait at least 10 ms for the reset process to complete.
7. Program the PRST bit in OTG_HS_HPRT to 0.
8. Wait for the PENCHNG interrupt in OTG_HS_HPRT.
9. Read the PSPD bit in OTG_HS_HPRT to get the enumerated speed.
10. Program the HFIR register with a value corresponding to the selected PHY clock 1.
11. Program the FSLSPCS field in OTG_FS_HCFG register according to the speed of the
detected device read in step 9. If FSLSPCS has been changed, reset the port.
12. Program the OTG_HS_GRXFSIZ register to select the size of the receive FIFO.
13. Program the OTG_HS_GNPTXFSIZ register to select the size and the start address of
the nonperiodic transmit FIFO for nonperiodic transactions.
14. Program the OTG_HS_HPTXFSIZ register to select the size and start address of the
periodic transmit FIFO for periodic transactions.

Вземи подкарай примерчето от библиотеките на ST.
След като тръгне подменяй елементи от него с твоите и гледай кога ще се спре. Така ще стесниш периметъра на търсенето.

теглих един вентилатор на риференс менуала. според мен трябва да имаш външен ключ и евентуално повдигачка до 5V.
документа е малко объркващ и само един вентилатор не е достатъчен.
FS главата препраща към схема на връзване в HS главата...

И при мен така изглежда, но и старият така изглежда?
